[edit] Prefertilization effects
The combined Pill primarily prevents pregnancy by preventing ovulation. In women who take the pills correctly, ovulation is prevented in 98-99% of cycles. Forgetting to take one or more pills increases ovulation rates; one study found skipping two pills in a row resulted in ovulation in 29% of cycles.[46] (In women not taking the Pill, pregnancy occurs in approximately 25% of ovulatory cycles.)[47]
In the event of breakthrough ovulation, secondary contraceptive mechanisms are believed to come into play. Proposed secondary mechanisms active before fertilization include thickening of cervical mucus, which can prevent or slow sperm entry into the uterus, and changes in tube transport inhibiting sperm migration to the fallopian tubes.[48]
[edit] Postfertilization effects
Mechanisms that act after fertilization are controversial; according to those who define pregnancy as beginning at fertilization such mechanisms make the method abortifacient.

If you define life at conception, will you change your mind on accepting birth control? Now that you have the knowledge that conception CAN occur?

the question is, now that you have the info that conception can occur, do you still accept the pill as contraception? I ask because I keep reading how the pill os OK because conception does not occur. Well, now that you know that it DOES occur, are you willing to denounce the pill?

so, no one wants to answer the question? That{s OK, all I wanted to do was EDUCATE people to their beliefs and the facts. It helps, when you want to judge others to have the facts
