If you take your birth control pills every day, (you don't miss any) you are very unlikely to become pregnant. That's because birth control pills are 99% effective if taken correctly. Remember, you're still at risk for getting an STI unless you use condoms 100% of the time.
Similarly, you may ask, does he need to pull out if I'm on the pill?
The biggest advantage of pulling out is that it's convenient. You don't need any condoms, birth control pills or other items to practice the pull out method. Instead, your partner just needs to pull out before they ejaculate.
Also to know, how do you prevent pregnancy after being nutted in?
Using birth control AND condoms together is the best way to prevent pregnancy AND STDs. If you want to keep using the pull-out method to avoid pregnancy, you should also use condoms in case there's sperm in your pre-cum or you don't pull out in time.
Does the morning after pill work if he came inside you?
It does not prevent pregnancy for any unprotected sex you have after taking it. If your girlfriend takes the morning-after pill and then you have unprotected sex, she'll need to take emergency contraception again.
Can I finish in my girlfriend if she's on the pill?
The pill works by preventing ovulation, which means that there's no egg for sperm to fertilize if it gets inside your vagina. So to answer your question, if you're on the pill, you're protected from pregnancy, even if semen gets in your vagina.
