Bad cramping


I made a post before but never really got much feedback from it about my period. In my last post I talked about how my period has been off the past 2 months and I havnt gotting a period in a while and I did have 2 days of light spotting that went away basically as soon as it started. I’ve taking pregnancy tests all negative. Recently since all that has happened I’ve been having terrible cramping. It was on and off cramping but today I started having cramping that turned into severe cramping. I took 2 gel Advil and it hasn’t eased the pain. I tested again yesterday on a test strip since me and my husband have still continued to have sex since I havnt gotten a period and still got negative! Is anyone else experiencing this or have experienced it and figured out what was going on?
