T M I. Spotting

I'm currently 9 weeks pregnant. I found out when I was less than 5 weeks. I had been spotting light pink for a couple weeks intermittently bit for the past week or week and a half, I've been spotting red. Not a lot and not everyday but I've noticed it's usually after a BM. But I'm not constipated, so it's not like I'm straining. I had my first appt and transvaginal u/s a week ago and I brought it up and was basically told they couldn't do anything but wait and see. They didn't seem overally concerned. I go back in two weeks for another u/s. Anyone else have this experience?
