Bleeding after sex? 36 weeks exactly

So after sex I noticed a super small amount of blood. Kind of bright red. Id say no more than half a dime size amount. About an hour later I went to the bathroom and wiped and there was some more but not as bright and I think I saw some super small clots in the toilet? Everything that I've read says it could be an irritated cervix/dilating/mucus plug. I'm 36 weeks today and I see my doctor tomorrow. Anyone else experienced this? Baby is still active and no cramps or anything so I'm not too worried yet, however this is my first so I'm also not sure what to expect at this point.
