I have been on the birth control Cryselle for 3 months and I am on my second week of my 3rd pack. my boyfriend and I had sex but the condom broke. The ejaculation didn't stay in me. I was scared and paranoid so I took plan b. How effective is my birth control and taking plan b for preventing pregnancy and how much of a chance is there that I could be pregnant? How late could my period be??
I think we'd have to be God to know the answers, I'm afraid. The contraception pill is in the high 90%+ in terms of reliability, & Plan be is most effective if taken within the first 12 hours, when it is 95% effective. 12-24 hours is 85% effective, & 48-72 hours drops down to around 75& effective.
Your period could be up to several weeks late, & you may experience some bleeding caused by the Plan B, before you get your period. It could be light spotting or brown discharge, or could be a proper bleed, from light to very heavy flow. Your actual period could be different in flow strength, too.
It's difficult to tell what is your period & what is Plan B bleeding, sometimes.
You didn't actually need to take Plan B, if you'd been on time with your contraception for the week before the accident, so I don't think you need to be worried.
