So my period was due yesterday and prior to that ive been getting headaches nearly everyday this month which is unusual. But besides that i havent gotten any of usual symptoms for getting my period which is cramping and mild sore breasts. My last period was February 21-24.. i had sex the 26 unprotected and then two days later i was getting cramps in my uterus. Just wondering whats going on. I dont see my doctor until April 5th. I dont want to get my hopes up but i would like a little insight to whats going on i havent been stressed out. Please help.
