Sorry for the question but...

How did you know you were having a miscarriage? What were the signs besides bleeding? I started spotting last Tuesday and over the days it started to be a little bit more.. A few drops every time I used to the rest room, Sunday I went in for an ultrasound and saw the bb, they said there was a heart beat and i was 6 weeks 4 days, but yesterday I started bleeding more not enough to put on a pad tho. Last night I used the restroom and I saw like a small long clot.. 4 in the morning I’m balling my eyes out... The bleeding has stopped now. But idk what to think? Am I going to have a miscarriage? I’m so scared and sad.. I know there’s nothing I can do right now, that it’s literally all up to God...
