The contraceptive pill changed the lives of women on an individual level, since the pill can reduce heavy bleeding, painful cramps or irregular periods. The combination pill makes it, in some cases, even possible to skip a period. Even though these advantages occur more often than the side effects, it is also very important and necessary to pay attention to this side of the story.
When discussing the risks of taking the pill, it is important to keep in mind that each body is unique and reacts differently. We can distinguish three types of side effects: we already mentioned some advantages, but there are also risks and temporary inconveniences. It is true that the pill can be dangerous in some cases. However, this is very much related to a person’s medical history and which kind of birth control pill they are taking. For example, for smokers it is recommended to use the progestin-only pill, since pills with estrogen can indeed lead to some serious sickness. Women who already suffered from breast cancer, blood clots, heart attacks, … are also advised against using the combination pill. These high-risk side effects happen but are not common. However, that does not mean that it is not important to stay informed. More information can be found here.
People who start taking the pill can experience some temporary inconveniences, such as headaches, nausea or changes in their periods. The pill is a hormonal form of birth control and the body needs some time to adapt to these new circumstances. If these side effects, occur and, to what extent, is also dependent on the brand of pill used. In most cases, these inconveniences disappear after two or three months. These temporary complaints are not exclusively linked to the pill, also IUD users can experience, for example cramping, back aches and irregular periods. Normally, this disappears again after three to six months, which is a seemingly longer period. Again, these are only some examples. More information on the side effects of the pill can be found here and on IUD's here.
