I'm afraid that i'm pregnant. May LMP is Oct 7, 2012 with a 33 days cycle. I know i ovulated last oct 28 because i have EWCM. Now it's 5 days before my period, i had 3 HPT done last Nov 3,5,&6 and all are negative. I had a slight headache, feeling bloated and gassy, & i experience leg cramps. Please help!
