Hi,
Welcome to HCM,
The causes for not seeing heart beat could be few. If you are not sure about your First day of last period, or your periods were not regular before you conceived, or you had delayed ovulation. In these cases, actually your
pregnancy could be less than 8 weeks, and if we do scan before 7 weeks, may bot be able to see fetal heart beat. It is also possible, not to see the heart beat, if you have lot of fat over your lower abdomen, you have
retroverted uterus, or your bladder is either overdistended or underfilled with urine. It also depends on skill and experience of your sonologist. When we have this situation of not able to see heart beat, we usually ask patient to empty the bladder and do scan trans vaginal. By this route, we can diagnose heart beat even at 6 weeks. The worst possible thing is that, your baby is not developing and as your previous Doctor diagnose it as
Missed abortion.
Ecotrin helps in getting proper blood supply to the foetus and it is given in all those women who had prior mishaps of pregnancy and high risk pregnancies. It may help your baby, if it is not already missed abortion. it is wise to wait for 2 weeks and do repeat scan, before you take any decision to go for cleaning of womb, unless while waiting you start bleeding, pains,
dizziness etc.
Hope you got your answer.
