Hello dear I understand your concern Delayed period and abdominal pain could be due to premenstrual symptoms, ectopic pregnancy (if you had unprotected sexual intercourse in fertile phase), any other abdominal pathology. I would suggest to consult the gynecologist and undergo vaginal examination, abdomen examination and USG scan to rule out the cause. If USG will be normal then it could be due to premenstrual symptoms as it is caused by hormonal imbalance. I would suggest to take Tablet meftal spas two times a day Take bed rest Take healthy diet. Period can be induced by progesterone pill/shot in hormonal imbalance. Hope this may help you Contact HCM for further health query Best regards Dr. Sagar
