This past week i started waking up with headaches,I can't sleep,I have tender breasts,I have an increased appetite,My whole body hurts at times,The sides of my stomach hurt,I am not on any kind of birth control,I did have unprotected sex though about 3 weeks ago,But he did not nut in me,but then again there is pre-cum,i don't think i'm pregant,is there anything else that could be wrong with me?,and i don't think it's the flu because usually when i come down with something the symptoms are different and they are very consistent,any feedback is appreciated
