i was on birth control for about a year and went off of it June 2009 and had a normal period that month and the following two months. but now i haven't had one since august 2009. i have taken pregnancy tests and they have come out negative. and i have looked it up and found out that is normal to be 5 or 6 months before you start again...but i'm worried since its been almost a year since i have had a period. is there something wrong or will i start again soon
