My period was supposed to come on the 29th. I took plan b on the 16th of last month and bled the week after very heavily. I started birth control on the 26th of last month (i mean october lol) thinking it was my period a week or so early but had my actual period 2 days early on the 31st. Ive been taking my pill at the right time and havent missed a single one and had unprotected sex on the 9th, 2 weeks after starting birth control (it says to take for 7 days with added contraception). How likely is it i could be pregnant or is it just the hormones from the pill? I was on the same pill years ago and never had a period but why would my last one come and this one not? Would it be too early to test?
