I had my Last period on Jan 17th. Me and my boyfriend had sex on the 5th of this month.After he came we had found out the condom was broke. So the next day I went to the pharmacy and took plan b at 11am.On Sunday I had like a white vaginal discharge. I've had no symptoms from the pill. Basically I don't know what to expect next. I'm worried about all of this. What should I do and how does Plan B work??
