I feel like im crazy

Pd was late last month. Had unprotected sex 3 days after. 5 days after sex i started spotting. Its too early to tell with a test but I just have this overwhelming feeling that I could be pregnant. We aren't ready for number 2 just yet, so idk if its just me being paranoid or if its actually possible. I just feel bloated and am starting to want foods that Im not usually a fan of. I feel like im going crazy.
