Can she get pregnant if I ejaculate into her and she's taking pills?

Probably not since she's taking birth control pills. But there could be a very very small chance. Most likely not but you never know.

The only way to avoid pregnancy is abstinence.

The pill is 99 percent effective in preventing pregnancy. Even so, between 2 and 8 percent of women become pregnant each year while using it.

Here are five things that may cause the pill to become less effective or even fail:

- Not taking the pill at the same time every day
- Missing a dose
- Alcohol
- Antibiotics/seizure medication
- Taking a generic form of the pill

So women should be especially cautious and use a back-up, such as a condom, if they are put on any medication that may interfere with the pill.
