I had my period two weeks ago although it was slightly irregular, and I  have been almost constantly nauseous for the past week but I almost always feel hungry at the same time,  smells are unsually strong and I have been getting headaches quite frequently. Everything I find on the internet says pregnancy, but I find that hard to believe since I just had my period two weeks ago, and that is not enough time to have pregnancy symptoms, and is too early for a pregnancy test.   Does anyone have any idea what could possibly be going on with my body?
