I'm not sure what the chances are per se, but there are many cases of misdiagnosed missed miscarriages, especially with tilted uteruses. You might want to take a look at the website www.misdiagnosedmiscarriage.com, which has a number of stories of women whose babies' heartbeats were not found until much later in the pregnancy -- in one case, not until Week 13.
Hope this is helpful and that the doctors are wrong in your case.
Ive heard once there is a heartbeat the chances of miscarraige go way down.
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.
I would say that is a normal heartrate for 6.6 days - my 7 week scan today showed the heartrate at 154 bpm - this is apparently the upper end of the scale. Best of luck with your pregnancy and congratulations, it is an incredible experience.
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 you have had no cramps or spotting it is unlikely that you will have lost the baby between 6 and 8 weeks.
With my first child I was 7w3d when I had my first u/s. My second child I was 9 weeks. This coming Monday I will have an u/s @ 6w6d and hope to see a heartbeat. I heard from my Ob/Gyn that at 6w1d there should be a heartbeat noticeable on trans. vag. u/s.
You could see a heartbeat if they do a transvaginal ultrasound.
no it is impossible unless you die at 20 weeks
Absolutely a scan can tell the difference within 3 weeks at this stage. The heartbeat would be visible at both 7 and 10 weeks (which you would be pregnancy wise). Measurements are taken to date the pregnancy so you need to ask the doctor/tech/nurse how many weeks pregnant you are.
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.
I've read that it decreases to 3% after heartbeat is strong and detected at (or around) 8 weeks.
Nope, closer to 8-9 weeks
