Most of the pain in the abdomen after taking the pill is caused by adverse reactions to the pill. Some women may also experience nausea, vomiting, breast tenderness, dizziness, vertigo, fatigue, vaginal bleeding, and other symptoms after taking the pill, but usually these adverse reactions will gradually disappear after stopping the pill. It is recommended to relax, pay attention to rest and not to take oral contraceptive pills frequently by yourself. If there is persistent abdominal pain that cannot be relieved after stopping the pill, it may be related to gynecological inflammation, and patients should go to the hospital for corresponding examination and gynecological ultrasound. If there is inflammation, the patient can take some anti-inflammatory and pain-relieving drugs as prescribed by the doctor, and also check whether the abdominal pain is caused by abnormal function of the gastrointestinal tract.
