Some premenstrual symptoms, such as headaches, abdominal pain and nausea, are common in the first few weeks after starting the contraceptive pill due to major hormonal changes.

What to do: It is recommended you see a gynecologist when these symptoms prevent daily activities or take more than 3 months to disappear, as it may be necessary to change the type of pill.

2. Changes in menstrual flow

After starting birth control there is usually a decrease in the amount and duration of bleeding during menstruation, as well as escape bleeds between each menstrual cycle, especially in the use of low-dose pills that make the lining of the uterus thinner and more fragile.
