I am having irregular periods for the past 6 months. I took an ultrasound in November to verify PCOS but there was no such problem. I have spotting for initial few days and the last days. The period length has increased to 11/12/13 days from normal 7 days. Last month, my gynec doctor asked me to take contraceptives and I took them for 14 days post which I got normal bleeding period but for 11 days. I stopped taking them as I was having side effects. This month I got lighter period just for 5 days. Please advice what to do. I am married and I have a 2.5 year old kid (through cesarean). I never had any issues with menstraution in the past.
