okay, ive had my cycle every month ever since i was 15. as hard as it is for me to say it me and my boyfriend do have unprotected sex. i know we shouldnt do it because im not on the pill. as soon as we both got home from college we had sex. that was in may. i didnt have my period in june but it came in july and august and now it hasnt came since august 26. ive take two pregnancy test one in aug and one a couple weeks ago..if im not pregnant then whats goin on? could i have a sis on my ovary? for some reason thats wat i keep thinkin...
