Thanks for your query.
Very hard to put diagnosis just from few symptoms/signs. I noted you have had previously gastric disturbances and UTI. If your pain are correlated with previously condition or not need to be determine by properly check up to rule out above mentioned conditions. You must thinking also about premenstrual syndrome
that often appear with intense pain, cramps. However, I will advice you now at this stage abdominal ultrasound
, blood work, urine analysis and Gynecologist consultation.
Take care and if you have additional queries I will be glad answer you.
