I think you will be ok as long as have a heart beat. With my lsat full term pregnancy I went in real early around 6 weeks and had trouble finding a heart beat. Then I had severe bleeding, and I mean severe it just poured out of me super heavy and very bright red so I was balling my eyes out thinking I lost my baby well went in for US and this was around 8 weeks and found out was a hemorige and then found out that they could see two sacs now...but heartbeats were very hard to find so they were unsure if any of them were living anymore, so I went back in the next week and low and behold, there was still two sacs and you could see a feint heartbeat on one and a strong heartbeat on the other, I was still pouring blood, I did for months but I had to come back in two weeks later because one of the sacs looked way more developed than the other, sad to say though that the one that was feint heart beat and underdeveloped was no longer in my body two weeks later...But I did have one very healthy little baby after that and the morning sickness stopped after that....But I still think you have strong chances:D right now my baby is measuring bout a week behind due to all my complications but it is still extremely healthy:D So try not to worry and think happy thoughts, seeing/hearing a heartbeat is positive news:D keep us posted and wish you the best of luck. Remember, stress is bad..its a killer...so try not to stress..i know..its hard...I cant even take my own advice lol
