Im on the birth control pill yasminelle and for the last few months my withdrawel bleed has been very light and starting later and later each month. This month I did not get my period (I took all the pills correctly and also have been using condoms - none split etc) I also took 4 pregnancy tests which are negative. Just wondering has this happened to anyone else while taking yasminelle. i decided to stop the pill mid cycle and for 7 days and during that break i got a withdrawal bleed but it was brown and had some sort of tissue like stuff in it. i went back on the pill again. the last pregnancy test was taken 4 weeks after sex (which was protected) and it was negative. any advice?
