This is a very common question many couples often come across. The answer is simple. Birth control pills generally take about 7 days before they will prevent pregnancy. Some may work faster... some slower, so check with your doctor to be sure. To be safe we'd recommend waiting at least 1 month before being 100% sure the birth control pill has started working.
The next question we want to ask you is, why would you not want to still wear a condom? The pill is not 100% effective at preventing pregnancy. Sure, it's over 99% effect if taken exactly as you should, but forgetting to take the pill or not taking it at the correct time lowers that percentage dramatically. For the purpose of our argument lets say the pill is 98% effective at preventing pregnancy.
If we break that down to a number we can understand, for every 100 times you have sex 2 of those time would be like you had unprotected sex. Yea, that's a pretty safe number, but those are 2 times you could easily get pregnant. Now, if we add a condom into this equation it changes things drastically. Condoms are 80-98% effective. We'll just say for this example that they're 90% effective. Or, in other words, if you had sex 100 times with a condom it would act as if 10 of those times were unprotected.
Still following us? Good. If you wear a condom winch is 90% effective and you're on the pill which is 98% effective your chances of getting pregnant are very very slim. It's percentage of something like 99.9%. Basically, you would need to have sex 1,000 times before 1 of those would be like you had unprotected sex. Compared to just using the pill which would only take 50 sessions of sex before 1 of them being similar to unprotected sex.
The math... using a condom with the pill is 20 times safer then just using birth control alone. If you ask us, it's worth it to keep using condoms while using the pill. Even though birth control is much more effective then the condom, if both are used in conjunction with one another you will be far less likely to become pregnant.
