Just updating this thread so that anyone who ends up with a similar situation in the future has an answer.
I started having brownish bleeding 4 days back. The bleeding has turned into bright red so the doctor and midwife said I'm beginning to miscarry. My hcg 2 days back was 147. It's increasing but the increase is so slow and sluggish that they are now suspecting ectopic pregnancy. I'm in the process of doing more blood work to figure out next steps. My bleeding so far has been slow and sporadic.
While I'm emotionally very low knowing that I couldn't continue this pregnancy, I want to assure any other moms out there that not every case with low hcg count ends up in miscarriage. I read up a lot and it seems like there are a lot of moms out there who end up having happy and healthy pregnancy.
