Need advice, may be TMI

So I woke up in severe pain today, it starts in my lower abdomen and radiates all the way down to my vaginal area. It hurts worse when I try to stand up or walk , I’ve had two kids , not on birth control and never been diagnosed with anything. I’m also not due for another 2 weeks. Has anyone had this happen? Or should I set up a primary doctor appointment or go to ER
