35 weeks pregnant and blood??

Okay mommies, serious question and TMI. me and my SO just finished having sex and I wiped after peeing and noticed a little blood. Wiped again and there was more. But so far since wiping those two times I haven’t had anymore blood (but I’m about to go check again) but I have NEVER bled after sex this whole pregnancy and we didn’t even do it rough or hard. I’m 35 weeks and 1 day along. It’s not just spotting, i mean it’s bright red and it’s about quarter size amount of blood. Boyfriend is saying we need to go in to get checked. should I? Is this normal? Baby is moving fine but I’m still a little worried.
