Cramping and subchorionic hemmorage

I've had a subchorionic hemmorage since 5 weeks and I'm almost 12 now and I had gushes of red blood before and lately it's just been brown.
Today there was a decent amount of brown blood with small clots and light cramping, I haven't cramped at all through this pregnancy so I'm a little worried, I can't tell if it's my normal bleeding or.....idk I called my OB and he said there's nothing he can do so I just need to wait until my ultrasound in 5 weeks....I'm really scared and nervous
