I am a college student who may be pregnant. My cycle is about 29 days, and I usually start my period around the 4th or 5th of each month, but I had unprotected sex on September 17, and I let him finish inside me 4 times, because I didn't think I would ovulate until another week. I was supposed to start last Thursday/Friday, but I haven't started yet. I went to the dollar store and bought a pregnancy test but it was negative, and i took it on Friday mid-afternoon. Wednesday night, I had cramps off and on, and I woke up with hot flashes which is weird because i had my air conditioner on full blast. I've been feeling weird lately, besides the hot flashes which I never experienced, I've been sleeping more during the day, I've been eating a lot more than ever with a strange craving from time to time, like i would crave pistachios and chocolate ice cream together. I would eat and it would take me a long time to get full, my appetite was greater than ever. I've also had headaches on and off too. I haven't been to the doctor yet, but I will as soon as possible, i have no health insurance right now. What's your advice? What should I do?
