ok, so when i was 16 i started taking the pill and i stayed on it for 4 years. i stopped taking the pill in june after my boyfriend and i broke up (i knew i would not be sexually active and couldnt afford to stay on it anymore) and had a regular period in july. for some reason i did not get my period in august, but it resumed again in september and october. i was due to have my period on november 28, but it never came, and still hasnt after 29 days. i know that it is common to have irregular periods after stopping the pill but they should become regular after 3-6 months. december would is 6 months for me, and still nothing. has anyone else had this kind of problem? i cant be pregnant, and i havent my changed diet/excercise. i also have not been under any kind of stress. help? TIA.
