Is it happening again?

Sh
Sorry if this is the wrong group. I've had 2 miscarriages (one missed and one that went at 8 weeks and had to be taken care of medically.) 
I got a BFP this morning after a few very light positives early this week. This afternoon I started bleeding. It was pink spotting at 1st but now it's bright red and heavier. Am I losing another one? This is heart breaking.
