I had my last period 2 weeks ago it started on Jan. 14 or 16, I just know it was a math class day. I had unprotected sex a day after my period was over and then again 5 days ago (Jan. 25). 2 days after the last time I had sex (Jan. 25), so this would make it the 27th.. i had a lot of white/clear discharge just for that one day and i haven't had anymore after that... i am having cramps, my back hurts (kinda in the middle, sometimes in between shoulder blades.), my boobs hurt, and i get tired fast. with one day of a lot of white/clear discharge and no more after that a long with some symptoms...could I be pregnant.. or should i seek immediate medical help for something else.
