Very curious

Okay so the past few months my sex Drive has been slacking! Idk what’s wrong with me but I just haven’t wanted to have sex at all. I had some faint positive tests before my AF & then I started. It’s was normal length just a little lighter then usual not much but a little. The past 2 weeks I’ve literally been wanting sex non stop! I woke up this morning and I was nauseous. Is there a chance that I could be pregnant & that wasn’t AF?? Please no rude comments!
