Help please

So last month was crazy, I thought I could have been pregnant. Ended up bleeding two days around my period but was lighter, so I figured it was a period. Well I took two test, the ones you pee on a stick and couldn't pee long enough so idk. Just waiting for my next period. But now when I have sex with my boyfriend it feels like I dry up and is uncomfortable. I'm always in the mood so I don't understand.
