BFP but heavy bleeding....

We finally got our BFP!!!! However it is bittersweet 😔... I had what I believed to be a period the 15th-19th.... yesterday as I was doing yard work I felt some light cramping but didnt think anything of it, I assumed I was getting ready to ovulate. Then I felt a very wet plop in my underwear- went to the bathroom and I was bleeding very heavily and had some clots. my husband and I went to the ER. after several hours there I found out I was indeed pregnant, there was a small sack like structure in my uterus, but all still too early to tell. The bleeding did stop, and I could go onto have a normal healthy pregnancy - or the miscarriage could come on within the next few days/weeks 😓.... my blood hcg levels are 8-900ish right now and I'm supposed to have another blood text in the next 48hours to see if they are increasing..... please keep your fingers crossed for us!!!!!
