My period is late by 6 days which is weird bc it has always been here on the 10th of every month if not on the 11th. I had sex last month on the 16th and he came inside of me twice I was on birth control for a month already but on the day I had sex I missed the pill that whole day and took two the next day. However I missed another pill that same week. Days after sex, I started spotting. I took a cheap pregnancy test on the 5th day after my missed period and it came out negative. Could it be that it was a false negative ? Or could it be that missing birth control pills messed with my cycle ?
