Hi ! Good morning. I am Dr Shareef answering your query. If I were your doctor, I would advise you for an ultrasound of abdomen to rule out any pelvic pathology like endometriosis for this kind of cyclical pain. If you are sexually active immediately post partum, a missed pregnancy could not be ruled out and an ultrasound might help in that. If you eat from outside, avoid it as it might cause cramping due to intestinal infection.In case of persistent cramping, you could take a second opinion from a gynaecologist in your area. I hope this information would help you in discussing with your family physician/treating doctor in further management of your problem. Please do not hesitate to ask in case of any further doubts. Thanks for choosing health care magic to clear doubts on your health problems. I wish you an early recovery. Dr Shareef.
