Stinging and pinching?

Anna • Mommy to my beautiful rainbow girl❤

Okay so I'm 14dpo, no AF, negative tests... I just got the most intense AF cramps ever (like mid cycle need heat and pain killers now pain) and I ran to the bathroom thinking it's AF but nothing... A few minutes later I get a stinging pinching pain right in the spot below and while it was doing it I also had back aches that went away after a few seconds... Anyone had this before?
