Common Questions and Answers about Pregnancy calendar from conception

Avatar f tn When they give you an estimated due date, go home and plug it into an online conception calculator or just count back from it on a calendar 266 days. But don't wait, the difference between March 17 and March 24 is only a week, and by the time you're in your 12th week of pregnancy, the margin for error in using an ultrasound for dating purposes is a week. So you want to know right away. ps -- don't do this at the ER. Go to a good ob-gyn.
Avatar f tn All medical textbooks, computer-generated counts, and language used by doctors and nurses use that count even though modern technology now can help to pinpoint the conception date more accurately. That is why pregnancy, which takes 38 weeks from conception to full term, is still counted as being 40 weeks long. They add a spare two weeks at the front, to be able to calibrate the count to the presumed first day of the last period.
Avatar f tn You count back 38, the first two weeks of pregnancy is before conception...just remember that sperm can live inside us 5-7 days so whatever date you figure out, it's still better if you get that DNA test because you could still be wrong. Hope this website helps a little...I love it, just replace my due date with yours: http://www.pregnology.com/faralong.php?

341551 tn?1266984330 I've found some that tell you 3 5/7 weeks or ones that just say, you're in your 3rd week of Pregnancy but I'm looking for one that will say 3 weeks and 7 days or 7 weeks and 2 days..etc etc. Does anyone know of a site that does that? Thanks!
Avatar m tn count, as people just don't understand those because they start two weeks before the baby is conceived and it confuses the hell out of women), take the estimated due date home and put it into a conception calculator online or just count back 266 days on a calendar, and that will be your estimated conception date. It should show that you conceive after your period in March.
6295353 tn?1395245095 I tried one off google and it went off my due date because i don't know my conception date and it said i was having a girl.. which one did you use?
Avatar m tn But if you just got the due date from a calendar, or from ultrasounds later in the pregnancy, then there is no way to know which event produced the baby. If it is question of paternity, a DNA test will show what you need to know.
Avatar m tn From the ultrasound, they should also be able to give you an estimated due date. You can count back on a calendar 266 days from that date to get to an estimated date of conception. If you get an ultrasound and the doctor or the tech says "You're 7 weeks pregnant," just keep in mind he or she is not saying you are 7 weeks from conception.
Avatar f tn And yes at the hospital they told me my due date was April 7th I switched drs once and the due date went from April 7 to the 8 so only one day. Can I count on accurate conception from my first due date at 10 weeks? How far off will it be?
Avatar m tn At what point in pregnancy did you get your due date, and how was it determined? If it was by an early ultrasound (within your first trimester), the dates given by Dominique will be reliable. If it was just computed on a calendar from the first day of your last period, they might not be as reliable.
Avatar f tn Calculators don't say *you* are fertile from date x to date y. They say the possible window of conception is from date x to date y. That is partly to allow for the fact that some women will only have later (less accurate) ultrasounds to use for trying to compute their due date, and especially because of the long life of sperm in the woman's system. Say a calculator said your most likely or most probable date of conception was the 1st of the month.
Avatar f tn Hi, Janjan, You do know that pregnancy is dated from the first day of your last period, right? Doctors count from the first day of your last period, or from the presumed first day of your last period if they have an ultrasound in hand that places the baby at a certain date. When a woman tells her neighbor, "I'm 11 weeks pregnant!" she is likely also using that counting system, because she gets that count from her doctor.
1432741 tn?1300202363 INTRODUCTION This week your baby is undergoing some extraordinary changes and developments. The head, heart, spinal cord, and some of the larger blood vessels begin to form. As these blood vessels form, the heart begins to pump fluid through them, and your baby's first red blood cells are created. Your baby is about 7 - 9 mm or 0.27 - 0.35 inches in length, (approximately the size of a grain of rice), and weighs about 1/30 of an ounce - less than a breath mint.
358455 tn?1277437219 I did it on both possible conception dates since my babies were conceived 2 days appt and according to it I should have been having 2 boys but I'm having a girl and a boy....don't get the intelligender test either it said 2 girls and that was wrong to....
Avatar f tn How early in the pregnancy were you given the due date? Was it from an ultrasound or a little wheel or a calendar?
Avatar m tn I did a conception calculator and it put me around the same date, I had another nurse do a conception calendar and it put me on dec 30. I then had a second ultrasound and she was said I was under five weeks. Both u/s techs said if I had conceived on Dec 15, they would be seeing much more on these ultrasounds. How reliable is this? Who is the father? This is dire as a detail in my decision.
Avatar f tn You will be able to plug the estimated due date that was given to you by your doctor from the ultrasound into a conception calculator, or just count back 266 days from it using a calendar, and it will give you an estimate of when you concieved that is much better than a pee test that merely takes your hCG number and matches it to some averages and spits out a number of weeks.
Avatar f tn Was it from an ultrasound, and if so, how early in the pregnancy was it? If the due date came just from the calendar or a little wheel, or if it was given to you later in the pregnancy, there is a margin for error on the calculation of estimated conception date.
Avatar f tn How did you get your due date? Was it from a calculator or calendar, or did you get an ultrasound? If so, how early in the pregnancy was it?
Avatar m tn You can count back 266 days on a calendar from the estimated due date and get an estimate conception date, or use a conception calculator online. From you saying 8 weeks 6 days on June 15, I get conception as being on April 28, which makes plenty of sense given you having sex from April 22 to 25. (Not only is there the margin for error mentioned by the doctor but also, sperm can live up to 5 or 6 days in a woman's reproductive tract.) It just all adds up.
Avatar f tn They would start the count, count in two weeks, and assume conception came at the 2-week point. That's why a pregnancy, which is 266 days from conception to full term, is counted out as being 280 days by the medical way of counting. They put the 14 days at the front end, to move the count back to the first day of the last period. (Two weeks being the presumed allowance of time an average woman has between her period and ovulation.
Avatar f tn The way doctors count pregnancy, a month pregnant means about two weeks since conception. If the ultrasound tech or doctor said you were x weeks x days "pregnant", that count begins on the first day of the last period you had before getting pregnant. The count is done this way because the period is a big, obvious signal, not because the doctor thinks you are pregnant when you are on day 1 of bleeding. (He knows you weren't pregnant then, you were having a period!
Avatar f tn That's why pregnancy, which takes 38 weeks from conception to full-term birth, is counted as being 40 weeks long. They add a spare two weeks at the front to count things back to the presumed first day of the last period, so they can use the standard charts and graphs to measure the pregnancy's progress. That medical way of counting might be confusing at first, but it is how all the computations and textbooks are done, and that is why it is still used.
Avatar f tn Hi, annieamy, did you have an early ultrasound? Like, sixth or seventh week? If so, when was that (calendar date) and what due date did they give you then?
Avatar f tn I wish you a happy and healthy pregnancy. I will not strees myself out for what I did, thanks. And Im sorry for all the same comments my phone posted by accident.
Avatar n tn Well, you usually are most likely to get pg on days 12-16 of your cycle...from the 1st day of getting af. Your best conception date would probably have been around 3-25..so it may have been too early to concieve. Hope this helps!
Avatar f tn It is possible to bleed in early pregnancy. However, usually an ultrasound report gives the date of the first day of your last period, not a conception date. Please be sure "conception" date is really what you are reading; it is unusual for an ultrasound to date a pregnancy from a presumed date of conception. Also, when was the ultrasound done? If it was recent and you got pregnant six months ago, it is very normal for an ultrasound to be off by a few days.
Avatar n tn Just a guess of course, and since your periods are not regular, it may be harder to tell. I hope you get more help from the doctors. All the best to you!
Avatar f tn This is all confusing, Gsp. Your sono on Sept. 17 is most likely VERY accurate, and if you count back to you being 5-6 weeks pregnant on the 17th, that would put conception between Aug. 20 - 27. In there. One confusing thing, you give yourself two "free" weeks at the beginning of a pregnancy - pregnancy dates back to the last regular menstrual cycle. So the day your period is due, you are already considered 4 weeks, not the true 2 weeks you are actually pregnant.
