I had my daughter 7 weeks ago, I breast fed/pumped & supplemented with formula! I just stopped breast feeding this morning & had sex for the first time this afternoon! We didn't use protection, only the pull out method! I took Plan B 3 hours after sex! What are my chances of getting pregnant & when should I start my period?

There is not form of birth control on the market that's 100%, and that includes Plan B. There is no way to tell you what your chances of getting pregnant are, just that there is a chance. The pull out method is not a birth control method, there are plenty of sperm in early fluids to get you pregnant.

The Plan B will screw up your menstrual cycle. Also, you just gave birth and you did breast feed which can stop your period altogether. There's no way to tell you when you should expect your period.

You'll have to wait and see.

Plan B can make you miss your period, one or two months, one of the side effects, (or you may have a period next week, other way side effects sometimes work) The morning after pill
