Thanks for the query to H.C.M. Forum. Pelvic pain
radiating to hips , irregular bleeding, headaches
, on birth control , so such type of stomach may be due to .
1 Fibroid in uterus , diagnosis can be confirmed by ultrasound
of uterus .
2 PCOD or infection of fallopian tube
, diagnosis can be confirmed by ultrasound of both ovaries with tubes.
3 Irregular bleeding present with pelvic pain so may be due to hormonal
imbalance , diagnosis can be confirmed by examination of blood for eastrogen, androgen, F S H/L H ratio.
In my opinion consult a gynecologist and get his opinion as physical examination is very important in this case.
Good luck. Dr. HET
