My fiancé and I do occasionally have unprotected sex, but he always pulls out. I have stopped taking birth control a few months ago due to some health issues. I got my first period in years last month but according to the app I am now late. I have been feeling extra tired, bloated, and nauseous. Im only 2 days late but im paranoid. I did take 2 tests but both were negative. Am I just going crazy?
