Went for ultrasound last week! Measured me at 5and5, saw the heartbeat and it was 122bpm! I have to go back on the 20th for a follow up because they think I either had a twin that I lost or I have scar tissue(called uterine synechiae). I really think I see 2 sacs? What do you all think?! The doctor said she doesn't think it's truly scar tissue because I have never had a surgery or delivery! Ekkk I just don't know! I'm a nervous wreck this is my rainbow baby!
