extra fluid in uterus??

I had an ultrasound at 6weeks 6days. We saw a fetus with heartbeat. My ob called me later and told me everything looked good, but they did find extra fluid in my uterus, which he wasn't concerned about, but said he would do a follow-up ultrasound at 10 weeks to check on it. I saw it on the ultrasound becuase the technicians were talking about it, and it looked to me like a sac of fluid. Any ideas on what this could be?? Thanks.

Could it be possible you had another baby (a twin).But lost it.

I'm about 4-5 weeks pregnant and my doctor saw fluid in my uterus also. I'm not worried about it.  I don't know...I'm doing a lot of research on it myself. I'll let you know if I find anything interesting/might help.

I just had an u.s. at 8 weeks and they saw the same thing.  They didn't tell me much but want to re-scan in 10 days.  I was wondering about it being another baby that didn't survive as well.  The tech just said that it is usually just a fluid sac and it usually goes away.  However, she didn't give me much more info besides that.

I had a cyst removed on may 3rd of 2010 and now the doctor says i have a fluid filled sac in  my uterus without any fetal pole. my doctor called to have me do a hcg level but found all to be negative. i also have a fibroid and free fluid in my uterus. i now have to go in for a hysterectomy on august 3 2010.

I had 3 positive home pregnancy tests, I went to the doc and got an ultrasound and there was a fluid sac.  I got a blood test and it was negative.  The only thing I don't understand is that I'm on the mirena...I've had all the pregnancy symptoms!  Anyone else have this problem???

Were these miscarriages or did you have healthy babies? I'm 8 weeks and have the same thing & bleeding with no cramps. They say it's a miscarriage, but have read so many stories about misdiagnosed miscarriages and people who had regular, period-like bleeding throughout pregnancy and still had healthy babies. Please update. Thanks!
