Believe that my ovulation day is the day when we had sex, I took Plan B 3 hrs later but we had sex again on the next day. Is Plan B will works that way?
No. 1st - The Manufacturer warns that you are not covered for sex that you have once you have taken Plan B.
2nd - Plan B is the wrong type of emergency contraception to use if you are fertile or ovulating. You need one of the other 2 methods; either the other pill, Ulipristal Acetate, or to have an IUD fitted by a doctor. Either can be effective if done within 120 hours/5 days of the unprotected sex.
If your periods are regular each month, then your fertile time of the month is somewhere between days 7 - 16. Day 1 of your menstrual cycle is the 1st day of your period.
Most women ovulate (release an egg) around days 13-16.
In the days leading up to that ovulation, your cervical mucus changes, so that it can save any sperm you come into contact with, ready for ovulation.
That means that you can get pregnant from sex that you had up to 7 days before ovulation. That's how long the sperm can live in your body.
The way Plan B works, is to delay your ovulation, until the sperm has left your body. If you're already ovulating, then it can't do that. That's when you need one of the other 2 methods.
Without using one of those other 2 methods of emergency contraception, in the 120 hours period you have to do so, there is a strong chance you will become pregnant. It was the worst possible time of the month that the unprotected sex happened.
