Intense Pains? 🤔

This morning in class I had this very sharp pain/cramp in my lower abdomen/uterus area. I had to like straight & stretch for it to pass. It was SO weird.

Well I thought nothing of it. Then today we were in the city all day. After dinner (deep dish) we got up to leave and as I was walking out that pain hit me hard again.

I’m talking curled over pain in the street - it hit me like 3-4 more times over an hour.

It’s pretty much settled now (hour later) but I’ve been sitting.

Has anyone had this before their AF? Mine is due 2/17 (Sat) - or anyone had pain like this with implantation?

We are TTC & I took a test today (around 10 DPO it was a BFN). Trying not to symptom spot but I never have pains this bad I have to stop walking for a few seconds.

Opinions?
