Yes you can I have had a few cousins that have misscarried at almost 4-6 months. miscarring is most common in the first trimester with is your first 1-3 months of pregnancy. So is it possible at 8 weeks ..Sadly yes it is...
If there is no heartbeat by 8 weeks then you should schedule an ultrasound to make sure the baby is healthy. If you already had an ultrasound then chances are you might miscarry. There is no medical treatment to keep you from miscarrying, and it isn't your fault in anyway if that is the case so don't blame yourself and keep trying.
If they say you are still pregnant then you probably are. Seven weeks into the pregnancy is nothing. You have to take into consideration that they are going by your last menstural period when you could not have been pregnant so in actuality they are adding on a few weeks. Don't worry about it and try not to be stressed because stress is horrible for your unborn fetus.
You could see a heartbeat if they do a transvaginal ultrasound.
Three weeks pregnant is a week before you miss a period so it is impossible to know it is twins. If you are three weeks after conception, (5 weeks pregnant)it is still early to see a heartbeat.
Fetal heartbeat
An ultrasound at 6 weeks should show a fetal heartbeat, if there was a fetal heartbeat you're not miscarrying.. It's probable you estimated your due date wrong.
It would be crazy to see any heartbeat at five weeks.
You really need to talk to your doctor or the person who did the ultrasound about this.
At 8 weeks I heard my baby's heartbeat..., but at 14 1/2 wks I saw it on an ultrasound. :) Hope this helps!
If the heartbeat is not visible at 11 weeks on an ultrasound, that would be cause for concern. The fetal heart begins beating approx. 22 days after implantation into the uterine lining. An ultrasound done at 6 weeks will confirm a viable pregnancy and you would be able to see the heart beating.
No 6 weeks is very early for a scan which is most likely why he would like to see you again in a weeks time.
No, I didn't hear my babies heartbeat until I was about 14 weeks. It also depends on how much belly fat you have. I had some belly fat so maybe that's why it was a little longer for me. Don't worry everything will be fine.
