Headaches in women: The Contraceptive Pill
There are two types of contraceptive Pill. The combined Pill contains oestrogen and progesterone, whereas the so-called ‘mini-pill’ contains progesterone alone. The mini-pill avoids the problems and side-effects associated with oestrogen, but at the expense of a slightly lower level of protection against pregnancy, and much poorer monthly cycle control.
There are many different versions of the combined Pill, varying in dose and type of oestrogen, proportion of oestrogen to progesterone, and so on. The combination that suits one woman may not suit another, so if you find one brand of Pill gives side-effects, often all that you need is to change to a different brand.
There are many potential side-effects of the combined Pill. These can include bloating and abnormalities of menstrual bleeding.
