Avatar f tn If it was a sixth-week or seventh-week ultrasound, the projections from it could possibly be spot-on, but even by the tenth week babies begin to develop at different rates. By week 12, it can be +/- 7 days either direction. Correct me if I am wrong about your dates -- September 21, date projected by an ultrasound to be your conception date September 23, sex with guy #1 September 27, date projected by 10w4d ultrasound as conception date September 28, sex with guy #2 Is this right?
Avatar f tn 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. Pay out of pocket if you have to, but get the ultrasound right away. If you don't, the only other way to determine paternity is to wait until the baby is born and do a DNA test.
Avatar f tn that will atleast help you out with the conception date more. (just remember they start the dating of your pregnancy 2 weeks before conception.) But you will have to really get the DNA testing to be 100% sure.
Avatar f tn can a pregnancy test show up 1 week after actual sex?? also can a vaginal scan pick up sac 2 weeks after sex??
Avatar f tn with my 3rd pregnancy before i miscarried it was 1 week after conception that i got bad nausea and gaging reflex and tired all the time. but it vary in women and some women dont even get pregnancy symptoms at all. so maybe 1-8 weeks after conception that you could get pregnancy symptoms.
Avatar m tn Hi probably a question you hear alot but never the less i need to ask, my girlfriend fell pregnant very soon after i met her the doctor said her probable conception date was the 10th-18th november although she sufers with iregular piriods this made the due date the 7th august i didnt have sex with my partner till 26th november so by doctors dates puts me out by over a week altho he was actualy born 2weeks after the 7th august so 2 weeks late is it possible doctors dates could be out could he be
Avatar f tn I'd say conception is january 29th as well by the date. Early u/s are pretty accurate, but NOT perfect and can be off up to a week.

Avatar f tn There is a slight possible margin for error by the 9th week when using an ultrasound to try to determine when a person conceived, it could be plus or minus two days. Even if you knew for sure you did ovulate on the 27th, it sounds like your husband and the other guy are pretty much equal possibilities since your husband and you had sex on the 25th. Unfortunately there is no way to rule anyone out.
Avatar f tn you would probably ovulate about 14 days before the start of your cycle. But a pregnancy is dated from your last months period. And conception doesn't happen the exact time you have unprotected sex it can take 7-10 days after you ovulate. Why do you want to know when you period would come, if you already pregnant. You don't get a period when pregnant, you can get bleeding and spotting in pregnancy but not a period.
Avatar n tn o by the time my next period was 2 weeks late i was 6 weeks along
Avatar m tn It does sound like you were already pregnant by the 11th. Your conception window based on your due date is November 29 to December 7. If you were to try to compute from your period instead of from the ultrasound (which is never a good idea), it would put the window even further back.
1844903 tn?1318899048 Ive only had two natural periods in my life. One when i was a sophmore and one the second week of September 2011. I went to the doctor and they did a pap and took blood and said everything was fine but they put me on birth control, this was in January 2011. I took the birthcontrol for a month and had a peroid in Febuary of 2011. I stopped taking it after a month because i cramped so bad. Am i able to concieve?
Avatar f tn Sperm can live for 5-7 days, and the conception dates they give us aren't exact to the day...if they're even off by a few days, you see the issue? You simply need more time between guys to know for sure. By the way, pretty sure the conception date they gave me was 5-7 days off. Most women really don't know the exact day they conceive, the doctor's just giving you an estimation.
Avatar n tn And do you remember the first day of the last menstrual period of your mother of your son on the month of conception. The estimated date of delivery or birth is determined by taking the first day of the last menstrual period then adding 40 weeks to that date plus or minus about 2 weeks. It seems that if your son was conceived around Novmeber 3rd then August 14 could theoretically fall around the EDD of July 26th plus 2 weeks.
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?
Avatar m tn Whether the u/s was at ten weeks or eleven weeks, it still puts conception in May and not in April, and your doctor is not going to confuse your 34th week with your 37th week. I am not sure what more anyone on the Internet can say if you aren't willing to take your doctor's word for it.
Avatar f tn Your conception week would be around June 8th. If you google "conception calculator by due date" you can enter your due date and your conception, ovulation, implantation, LMP come up. They're approximate, of course.
Avatar f tn When I put my LMP in it says I would be in the first week of pregnancy. Now I know this is extremely early, but I really think I might be pregnant. Did anyone else have any symptoms like these, and this early? My pregnancy test said negative, but I know it's too early for it to pick up the hormones anyways. Please give me feed back! Thanks!
Avatar n tn Vaccination before conception is important, however. If you develop rubella during the first 20 weeks of pregnancy, your baby has a risk of developing congenital rubella syndrome. This condition can result in miscarriage, stillbirth or severe birth defects. Although there is a theoretical concern for the baby if you're pregnant at the time of vaccination or conceive shortly after, the risk of vaccine-associated defects is negligible.
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.
143123 tn?1274304425 But I'd take the doctor's estimate as pretty good, maybe off by a week. As the scans and so forth go on, they will be able to try to narrow it down a bit, based on standard size of the baby at those points. That's about all you can do to get a date, if you genuinely have no idea and a wide time range when it could have happened.
349463 tn?1333575176 I found a great book that was mainly pre-pregnancy information. It's called The Mother of all Pregnancy Books, by Ann Douglas the paperback is $15.99. Like I said the majority of the book was on pre-conception tips and advice. Best of luck to all of you who are trying this month.
Avatar n tn Hi everyone! I'm still trying to figure out what week of pregnancy I'm in. I had a complete miscarriage Feb. 19/07 and then ovulated on Mar. 5/07. I got my BFP on Mar. 17/07 so I'm still trying to figure if I'm in the 4th week or 5th week or what. If anyone could help that would be great! Thanks!
Avatar n tn does anyone know how many days not weeks are ultrasounds off by at a 13 week scan?
