Spotting at 28 weeks (ftm)

Gabrielle

I’m 28 weeks and 5 days. Last night I peed and when I wiped there was bright red blood on the toilet paper, not alot about the size of a dime and not thick at all. I wiped three more times and it was gone. It’s now the next morning and still no blood. I haven’t had sex. Is this normal or cause for concern?
