So i had unprotected sex with my partner about 12 days ago. I have head aches. Back pain. A little bit of nausea and im very sensitive to smell! I took a few hpt and they all came out negative. I have an infection that is possible from douching while pregnant (sorry it thats TMI) i bled a little bit but not much at all today for the first time. Breasts are not swollen and i never vommited. My stomach is constantly cramping. Help!
