Hi everyone me and my boyfriend had unprotected sex on may 7th he did not ejaculate inside of me but he probably pre-ejaculated, I started getting tender breasts around may 11th. This could be pms cause I do get pms all the time before my period or it could be pregnancy, im not sure. I have no idea when my period is due, sometime i think at the end of the month. But because my periods are so irregular i have no idea... i have been having small cravings, tender boobs, constipation, and mood swings. I do not want a child since i am 16. PLEASE someone help me figure this out :/
