well just in the begining of the month i had something similar when i wiped i had something in the tissue that resembled more than just blood and i freaked but i called hte doc and he assured me that it was probably just some extra discharge or something. haven’t seen anything since. i’m only 23 weeks. but i also would call doc just to see.
I have had unexplained bleeding a few times during my pregnancy. The first couple of times I freaked out and went in, doc checked me out and u/s confirmed everything is ok. Doc said some women just spot and/or bleed during pregnancy. Call your doc anyways, as they will want to make sure there is no internal reason for you to be bleeding. I am sure everything is fine tho.
