I have irregular menstrual cycle. It can take around 50-60 days before I get a period again but sometimes it just takes 30-40 days. My last menstruation was September 22, 2013. I had unprotected sex last October 15, 2013. He didn't cum inside but I'm worried about the pre-cum. I took Nordette as an ECP (4 pills then after 12 hours, 4 pills again) on October 17th then I felt dizzy and nauseous for about 3 days. Last October 22, 2013, I had brown discharges. Is this just a side effect or my menstruation is coming already? Help!
