Severe cramping in my cervix!!

I was hanging out with my boyfriend and all of the sudden I am getting super painful cramps in my cervix and uterus. it’s almost bringing me to tears, I can’t really move too much and even when I breathe it hurts so bad. I do have endometriosis and I am idk probably 57 days late on my period I think I’m not exactly sure but does anyone know if this is serious or if I should be thinking about going to the dr I have a very high pain tolerance and I have cramps all of the time this is different though please let me know what you guys think my boyfriend even asked if he should bring me to the hospital idk
