I am a 21 year female. I have pcos, diagnosed 3 months before. My periods came on 16 Sept and they were due again around 18th Oct (my bday). I took medicines to delay my periods (4 days=4pills) is 14 to 17oct. Had sex (pulled out) on 18th. Got my periods normally on 20th-24th Oct. Had sex again on 26th (pulled out) and just to be sure, I had an ipill on 27th. Now I got my periods again on 2 nov though it is comparatively browner this time. Is this something to worry about or just because of the pills and pcos and the diwali and exam stress and exertion? Also I had been going to the gym but due to things, have missed it for 10-12 days now. Could this also be a factor? Please help asap.
