I Have Pelvic Pain For The Last Hours. I Feel

I have pelvic pain for the last hours. I feel like I'm having contractions every three minutes. I feel like something wants to come out my vagina. I haven't had my period for a year and three months. I'm not pregnant, had my annual gyno check up last month everything was normal. The pain keeps getting stronger and feel dizzy. (I had a baby four years ago and everything was normal) What should I do? Someone help me please I need answers
