This morning a new guy I've started to date and I had sex. He came inside me. I took the Plan B pill 2 hours later. I was readying information and saw that if someone is over 175 it might not work. I am 180. What are the chances that it will work for me?
In terms of weight, it's impossible to know if it will work for you. As your over the weight guidance, I'd suggest opting hire one of the other methods of emergency contraception; either the other emergency pill called Ulipristal Acetate or to have an IUD fitted by a doctor. Either of those things can be effective if done within 5 days/120 hours of the unprotected sex.
Aside from that, Plan B works by delaying your ovulation until the sperm leaves your body, which can take up to a week. If you're already ovulating then it can't do that. In that case you'd need one of the other methods of emergency contraception.
If your periods are regular then you will likely ovulate somewhere between days 12 to 17 of your menstrual cycle. Day 1 is the first day of your period.
Plan B is not as effective as regular hormonal birth control, it's simply worth a try in an emergency. Better than leaving it to chance.
