Hi,
Here is a good explanation of how birth control pills work; it is from the "Go Ask Alice" website at Columbia University:
"Birth control pills prevent pregnancy through several mechanisms, mainly by stopping ovulation. If no egg is released, there is nothing to be fertilized by sperm, and the woman cannot get pregnant. Most birth control pills contain synthetic forms of two female hormones: estrogen and progestin. These synthetic hormones stabilize a woman's natural hormone levels, and prevent estrogen from peaking mid-cycle. Without the estrogen bump, the pituitary gland does not release other hormones that normally cause the ovaries to release mature eggs. "
Regarding your question on the change the regularity of your menstrual cycle, here is what the Mayo Clinic says, "The pill prevents your body from making hormones involved in ovulation and menstruation. When you stop taking the pill, it can take some time for your body to return to normal production of these hormones."
The "pull out" method is not the most effective way to prevent getting pregnant. I suggest your partner use a condom and that you visit your doctor to discuss other birth control options that will not make you sick.
