Plan B

So ladies I’m having a crisis. I’m 17 and me and my boyfriend had sex and the condom broke. I am not hoping for a lecture I am just seeking support, if you are going to leave any comments about how I shouldn’t be having sex please leave them to yourself, I am scared enough and I would appreciate some hopeful feedback instead of negativity. Anyways I took plan b within a few hours after it happened. It is now 6 days later and I am experiencing cramps. This is the first symptom I have experienced, I am not sure if this is pregnancy or because of the pill. According to eve I had a 33% of ovulating the day this occurred. I know that plan b can cause changes in the menstruation cycle and I will take a test about a week after my period is supposed to come just in case it does not. If anyone could give me some reassuring hope that I’m not pregnant it would be greatly appreciated
