The strange truth about the pill
Every brand of combined pill on the market contains the same type of synthetic oestrogen, ethinyl estradiol, and one of eight synthetic progesterones, called progestins. Ethinyl estradiol prevents the body from releasing an egg every month, while progestins thicken the mucus at the entrance to the cervix and conspire to make the womb inhospitable. Even if an egg slips out and becomes fertilised, it won’t be able to settle down and start growing.
So far, so good. But though the hormones are effective at preventing pregnancy, they aren’t perfect matches for our natural hormones. The end result is that these synthetic versions also have effects that you would never get from raw progesterone.

Many brands of combined pill have four to seven inactive pills at the end of the pack that are a different color—these are placebos and some women choose not to take them.

Talk to your doctor about what she recommends. (All of this info also applies to “extended cycle” pills where you only get your period four times a year.)
