My last period was may 30 and lasted 4 days, my hubby and I had sex on june 11,12,13,14,and 15. The past 2 days, i've felt more nausous than I ever have in my life.. Mostly in the morning and evening, i've had major headaches, and white discharge all day today, my boobs feel heavy as bricks. Is this all in my head or could I be pregnant? I've been on birth control... On and off (i know thats bad, I just cant remember to take it) but we've decided that i'm going off it after I finish this pack, and we will t.T.C. I cant stand not knowing, I want to take a pregnancy test sooo bad.. I bought an e.P.T, when should I try it?
