Hi, Thanks for the query. According to your description the possibilities are : -Pelvic inflammatory disease. -Urinary tract infection. -Regular hormonal changes in the menstrual cycle. -Intestinal problems etc. If the pain and bloating sensation persists, consult gynecologist once and get examined. If she recommends go for ultrasound. With this workup, possibly the cause for your problem can be identified and treated. In case of presence of infection, you may need one course of antibiotics. Antacids and antispasmodics can give symptomatic relief. Take care.
