When my boyfriend and I had sex, the condom broke and so immediately after that: we called CVS to get a Plan B and we picked it up. I took the pill once I got out of the store and it was around 30-40 minutes after the condom broke. I had my period a few days ago (my period started on the 22) and my period is a little bit irregular because it does not fall on the same day every month (it's maybe off by a few days). I was wondering. what my chances of being pregnant are.
It's really difficult to give you an accurate answer, because your periods are irregular.
Most women with a regular, average length monthly cycle, are fertile somewhere around days 10 to 18, if you include the days leading up to the release of the egg, when your cervical mucus changes in consistency, in order to save any sperm you come into contact with, ready for the egg. For me, I ovulate on the 15th day of my cycle, & am fertile roughly from days 13 to 16. It varies from woman to woman.
Day 1 of your cycle is the 1st day of your period.
Plan B works by delaying your ovulation (release of an egg), hopefully until the sperm has left your body (days).
If you have already begun ovulating, then it can't do that.
In that case, you should use the other emergency contraceptive pill, Ulipristal Acetate. Either that, or have an IUD fitted inside your uterus by a doctor. Either of those things can be effective if done within 5 days/120hrs of the unprotected sex.
From the dates you've given, it's likely that you're in time for the Plan B to postpone your ovulation. However, because your cycle is irregular, it's impossible to be sure.
If your cycle is usually longer than monthly, then your ovulation is probably later than most.
If in doubt, get one of the other methods of emergency contraception I mentioned.
