Small Gestational Sac

Im really curious if any of you have had issues with your gestational sac during early pregnancy, and what the outcome was. Did you end up having a healthy baby to term??

So I went in for my first sonogram on Monday. Mr doctor and I saw the baby, saw and heard the heart beat!!! beating at 115 (which my doc and I thought was sort of slow, crown to rump measuring 6.6mm, which she thought was small, for the gest period (6w4d). I also had a subchrionic bleed appear on the ultrasound, which looked to me to mimic the shape and size of the gestational sac. Doctor told me that it was gestational sac detachment, which possibly explained why my HCG was low. However I have had no cramping or bleeding/spotting. She said we wait and see and scheduled me for an ultrasound on friday.

On my second ultrasound (today Friday), the bleed looks to have disappeared, but she had a new concern because now the gestational sac is small. The baby is taking up the whole space. the baby has grown to the appropriate size (10.5) and hearbeat is at 133. I'm 7w4d today. I asked my doc if this was going to constrict or cramp the baby. She said no. I guess I dont understand that. She said again 50/50, nothing that we can do, doesnt know reason for small sac and that we still are going to wait and see again at my next US on wed, look for changes with the gestational sac, but that starting in my 8th-9week, the amniotic sac should start forming.

She also started me on progesterone suppositories last night because my prog went down to 10.

so now im scanning the internet about small gest sac and there is hardly any info on it. i guess i should stop fishing before i psych myself out. I'm trying to stay positive.
