Nevertheless, some health care providers and pregnant women talk about the three trimesters to help give the pregnancy a time-scale; related closely to the important stages of fetal development, and also a beginning, middle, and end. Beginning In the first trimester the embryo undergoes most of its early structural development. Most miscarriages occur during this period, the placenta will takes over hormone production around week 12 from the corpus luteum.

So if you are only 5 weeks it sounds like your development is very good seeing both a fetal pole and hb. Did he mention what the heartrate was?? I am not sure what the "likely" fetal pole means because if there is a heartbeat then there is definitely a fetal pole there!! The hcg values vary so much that it seems it would be hard to gauge development by the hcg level except that they say you won't see anything on u/s until you are over 1000 or so. Best of luck.

I guess maybe someone could give me a better understanding but as far as i know in a true blighted ovum the yolk doesnt even appear? so the fact that you first couldnt see a yolk and now you can i would still take as a positive at this point... Just curious are you 4 weeks 4 days based on your first day of your last period? im just wondering because usually the gestational sac can be seen at approx 5 weeks, the yolk sac appears at approx. 5.5-6 weeks, fetal pole is around the 5.5 -6.

The fetal heart undergoes a considerable amount of growth very early in pregnancy. The most critical period of its development is between three and seven weeks after fertilization, when a simple heart tube assumes the shape of a four-chambered heart. In fact, the heart actually begins beating by the 22nd day of life.

m 6 weeks pregnant at the moment and i thought everything was going find until i got a call from my hospital telling me they needed to schedule me for an earlier appointment because when reviewing my ultrasounds they saw a problem with the fetus development. does anyone have any idea what this can mean? I would really appreciate it if you can help.

If your doctor is concerned about miscarriage, blighted ovum, or ectopic pregnancy, the gestational sac and fetal pole (if visible) will be measured to determine what type of development should be seen. The guideline is that if the gestational sac measures >16-18mm with no fetal pole or the fetal pole measures 5mm with no heartbeat (by vaginal ultrasound), then a diagnosis of miscarriage or blighted ovum is made.
