Hi - I'm 51 years old and since yesterday afternoon I've had this pelvic pain which comes & goes almost like contractions. It starts out dull to painful. This morning for 2.5 hours it was pretty bad but its subsided now and the pain isn't as bad. This is day 3 of my period. I thought maybe it was gas but I've gone to the bathroom 3 times since yesterday afternoon. I do not have any other symptoms. Would anyone have any suggestions?
