Do you still need to use condoms on birth control?

This is just a lay answer. You should always ask your Doctor.

You do for the first month because that's how long it takes for the pill to become effective. You also do if you are not in a monogamous relationship, as the Birth Control pill only protects against pregnancy, not STDs like herpes or HIV.

It is a very good idea to still use condoms while on birth control because nothing is 100% effective. Using the both of them together will increase your chances of preventing pregnancy. And birth control DOES NOT protect against any type of std. So for prevention and protection it is best to use a condom. I just got the birth control shot; my doctor said it should become effective after 24 hours since i was on my period. So you dont have to use condoms but you should to prevent yourself from getting STDs/AIDs. Also, there is that 3 out of 100 that just might have that accidental pregnancy....usually those are the people that are late on getting their next shot or taking a pill.
