Possible Miscarriage?

So I need advice on a possible miscarriage I may (hopefully not) be having. Tested positive on FRER on this past Friday. today I woke up to heavy bleeding but only when I urinate 🤔 it started at 8am then stopped so i took a nap and woke to cramps that were pretty bad but not awful, stronger than cramps I had been having previously but not as bad as mestrual cramps. Wanted to go to hospital but I already know there isn't anything they can do once a miscarriage has started. Still bleeding only when I go to bathroom, and now it like trickles or drips out but no tissue, etc. coming out. I was thinking a subchorionic hemorrhage, maybe? Does anyone have any experience with anything like this?
