Sharp pain in bun during TWW

Totally embarrassed to post this....Tried googling this and searching on glow. Couldn’t find anything on glow but did see some other women in a few other posts on other sites mention it.

My husband and I haven’t done anything adventurous that would cause it. I’m 10dpo and had some cramping today and have been exhausted today but aside from that no symptoms.

I got three sharp pains today in my bum - it’s like a shooting sharp pain inside.

Anyone had this before?
