I had unprotected sex 3 days ago today. Monday I started feeling really bad cramps, I was in work on same day which is monday I had a sharp pain on my right side of my lower back and also on my right side around my ovaries could that be ovulation pains?. Brownish/ Yellowish colored stuff has started coming out of my vagina and I just havent been feeling myself. My stomach feels kind of bloated and hurts so much. My stomach growls like crazy, even after I have finished eating, like if i haven't eaten for days. Ive been extremely tired no matter how much sleep i get and it feels like i have to pee like every half hour, I'm always farting. I have already been to the doctor for a pregnancy test which I knew was going to come out negative because its too early. Could i be pregnant? Can pregnancy symptoms even start after having unprotected sex after only 3 days? Please help!
