I'm on birth conrtol and on August 30th I had sex without using a condom. Ive been on the pill for a few months, but for like a week or two before i had been forgetting to take it and taking it at different times. On Septemeber 12th I got my period, it was lighter than normal and lasted until the 15th. After this I started taking my pills again, on the 21st and 22nd i missed my pills and then on the 24th I started bleeding again. Before this, I have missed 2 or 3 days of pills and I have never started bleeding after ( I know it is normal to have a weird period for 2-3 months after skipping pills, but it has never happened to me bofore). The bloodflow seems to stay quite light, mot was brownish than red, and sometimes isnt there for a few hours, and it has continued since today, the 27th.
