I was having sex with my boyfriend and the condom broke. I was on amoxicillin last month as well as pain pills for my wisdom teeth. I am on tri previfem and take it continuously, I don't take the placebo week. We had sex a day ago and he finished in me and I'm out of pills and don't have any refills so I won't have one until tomorrow. I took a pill I had extra from a while ago but from the third week in the pack. Should I go and buy plan b or should I just take two tomorrow?
