What should I do if my menstruation is irregular after taking birth control pills?

Irregular menstruation after taking birth control pills may be a normal reaction after taking birth control pills, or it may be caused by pregnancy or pelvic inflammatory disease. You need to go to the hospital for examination before you can get targeted treatment.

1. Normal reaction after taking contraceptives: Irregular menstruation after taking contraceptives may be a normal physiological reaction. If it is not very serious, you can observe it first. Generally, menstruation will gradually return to normal after two cycles.

2. Pregnancy: Irregular menstruation after taking birth control pills usually means that the menstruation did not come when it should have. At this time, you need to check whether you are pregnant. If you take birth control pills too late after having sex, the drug will take effect more slowly and fail to achieve the contraceptive effect. You may also be pregnant. The first sign of pregnancy is amenorrhea. It is recommended to use early pregnancy test strips on your own or go to the hospital for examination. If you are indeed pregnant, you should pay attention to rest more.

3. Pelvic inflammatory disease: Pelvic inflammatory disease may be a bacterial infection in the vagina. The bacteria will ascend to the uterine cavity and then enter the pelvic cavity through the fallopian tubes, causing pelvic inflammatory disease. After suffering from pelvic inflammatory disease, it is likely to cause irregular menstruation and even prolonged menstruation. You can use azithromycin, amoxicillin, cefradine and other drugs for treatment under the guidance of a doctor.
