A member asked:

My boyfriend came inside of me twice in these past few days. i have been on the birth control pill tri previfem (norgestimate and ethinyl estradiol) for about three months now. pregnant?

Probably not: Birth control pills can be up to 99% effective if taken properly. They are effective after the first 2 weeks of use, so you should be covered. If you have missed pills, then the effectiveness is diminished. If you miss a period, take a pregnancy test. Home pregnancy tests are accurate about 14 days after conception.

Birth control: In general, birth control pills are 99% (or more) effective in preventing pregnancy if taken every day as scheduled. If you are concerned about pregnancy consider having a pregnancy test done.
