How long does it take for birth control to be effective?

Asked by Shuichi (316points) April 1st, 2010

I’ve been on it for a month and 11 days and my boyfriend and I had sex a couple days ago. To be extra careful I took Plan B.. are we too paranoid? Am I safe to have unprotected sex?

Probably, but you could also punch him in the nuts when he’s sleeping.

Naw jk, your fine.

Normally it is suggested you wait a month before unprotected sex after taking birth control.

You should be safe, though.

Birth control will NOT protect you from STDs!

Be smart! :)

My doctor said after two weeks pills are effective. As long as you took them as directed, without skipping any or taking them late, you should be fine.

In the second month if you are taking them every day at the same time you should have no problems. You are either on the pill or you are not. It doesn’t build up in your body and take a while to take affect, like other drugs. In fact every month you take a break, get your period, and start all over. Every month is a new month on the drug. However, in the first month people typically start on Sunday, rather than a particular day of the cycle, and sometimes people need to get used to the routine of taking the pill every day, so in the first month many times it is recommended to use secondary protection because it is not an ideal pill taking month.

It kicks in the day after you are released from the maternity ward I believe.

hiya there, please dont worry im a nurse i work on the women and children dept, you need to have proteceted sexual intercourse for 7 days then after that you will be fine, and if you ever miss a pill please take precautions for 7 days after eg, condom, remember though the pill does not protect against sexually transmitted diseases, have fun, hope my qualified informaton was helpfull for you x

You are safe from pregnancy, but not STDs! You should always use a condom!

Exactly. Unprotected sex is exactly that. You’re unprotected from STDs. In terms of the pregnancy issue, though, you should be okay.

You should be fine. After a month the birth control is working the way it should be.

It should be listed on the information pamphlet that came with your pill.

Physicians usually advocate using a backup method for about three months after you first start the birth control pill (that’s also normally included in the pill’s instruction sheet). So I don’t think you are being too paranoid. But use a back up method next time so you won’t have to take the MAP again.
