If a woman is on birth control pills then there is no chance of getting her pregnant even if she undergoes sexual intercourse. This is because the birth control pills or best known in the market as oral contraceptives are comprised of synthetic forms of two hormones viz., either Progesterone alone or a combination of Estrogen and Progesterone.

Not only Estrogen and Progesterone regulate a woman’s menstrual cycle but also these hormones play a vital role in fertility and determining pregnancy.

If a woman is on the birth control pill or oral contraceptive it is less likely for her to become pregnant. If you are on these pills then you don’t need other protections like using of condoms during intercourse.

There is less or no possibility of becoming pregnant if the woman uses birth control pills regularly. This is because ovulation does not take place in most women who are consuming the pill.

Birth control pills are the best way of contraceptive protection and the chances of not being pregnant is 99% and above. Even if you forget to take a pill or skip an occasional pill, then also you won’t get pregnant.

So if you are on a birth control pill prevention of pregnancy is guaranteed.
