hi after you stop taking birth control pills the exogenous hormones will leave your body within a few days regardless of how long you were taking the pill. however that does not mean you’ll see your period by the next cycle. some women may not get their period for several months; this condition is known as post-pill amenorrhea (absence of period). since the pill has been preventing your body from making ovulation and menstruation hormones it can alter the normal production and your body can take longer to resume production. while this may sound like a great side effect (no period for months on end! ) you should take a pregnancy test if you’re sexually active since some women will ovulate and conceive before they ever have their first post-pill period. hope this helps you. good luck
period was over 70 days late got one last week but it was short. is there a chance that im pregnant? . i was on the pill for 4 years. went off it in november. december 9 was the last time i had a period. i just got in last week but it was very short. strong cramps and light bleeding for 2 days one day of stronger bleeding and cramps then 2 days of light brownish discharge. should i be concerned? or is it just a short period? when i was on the pill i was pretty consistent and it started strong basically from the start and would last for 2 or 3 days of heavy flow then light for 2-3 more days.
