dont worry youve heard the heartbeat!! :)
Seeing a heartbeat at 11 weeks is a great indication that things should go well. You're very close to your second trimester. I would try not to worry too much. I know, that's hard to do but try to enjoy it. It will go by very fast!
You definitely should be good if you saw the heartbeat. Try not worry everything will be ok.
My sister saw the heartbeat at 8 weeks with her first, then miscarried at 12 weeks. With this past miscarriage she was 11w4d and had yet to have a U/S, so she did not hear or see the heartbeat. They told her the baby stopped growing at 9 weeks.
If you saw the baby at 11 weeks, then I do not think that you have anything to worry about.
Have you looked up the stats on miscarriage after 11 weeks?
Also, with my sister's first m/c they did not know when the baby stopped growing. I say she m/c at 12 weeks, but there is no telling how long before that that the baby stopped developing. She had NO warning of a miscarriage. She woke up cramping really hard, then 2 hours later she passed the baby in it's sak.
DON'T let my stories worry you! My sister had quite a few health problems with both of her miscarriages. She had high blood pressue, gestational diabetes, and she was extremely sick with both.
I really do not think that you have anything to worry about.
