I'm starting to feel like it's all in my head.

I had what I thought to be my period the 12th & 13th. It was reddish orange & looked like EWCM. On the 13th I also learned I can lactate from my right breast. Now I'm tired & I can smell everything. I also have a headache & kinda sore boobs. I know these are pregnancy symptoms but the only time he came inside of me was the 5/6. Other wise all my sexual encounters was the pull out method. What the hell is going on?!? I really am starting to think all my symptoms are in my head.
