I've been on my pill (microgynon) for a few years now, I've been taking it non stop for the past 4 months due to my doctor prescribing me antibiotics and telling me to keep taking it and not take my break. I'm not meant to have my period for another week or so but I have started getting a mainly brown red discharge in my knickers and then when I go to the toilet It comes out as well. I done a pregnancy test in my doctors the other day and I'm not pregnant. I had sex with my boyfriend and then went to the toilet afterwards an there were brown red clumps coming out of me.... I was wondering if this is the shedding of the lining of my womb?
