I used to have normal periods of about 5 days, recentley the past two have been very VERY light, im talking as if there is no need to use a tampon or anything, its only obvious im on the "period" (withdrawel bleed) when i go to the toilet and even then its only noticeable by wiping. my boyfriend and i have been having unprotected sex and im worried i could be pregnant. i have no symptoms other than these light periods to make me worry about that (no breast tenderness,nausea etc). i have read about implantation bleeding,but surely having two abnormally light periods is not implantation bleeding? is it possible by being on the pill for the past 5 years i am now only having lighter periods?does sex change the amount/length of a withdrawel bleed?

Welcome to ehealthforum.
Contraceptive use can cause abnormalities in hormonal levels that might lead to bleeding abnormalities. If you have not been regular with your pills, then the protection may not be adequate, and there are chances that you might get pregnant.
The symptoms of nausea, breast tenderness, fatigue, spotting may not be present in every woman. Some women can feel them right within 2-3 days of fruitful intercourse, and some do not feel them at all.
Discuss about your abnormal periods with your healthcare provider/gynecologist, to see if it is really due to your birth control pill, pregnancy or some other cause.
Take care.
