Itching during/after period

Anyone else get really itchy down there during or after their period? Why does it happen? How do you relieve it?

I only get it on the last day of my period and maybe like 2 days after. There’s no strange discharge or odor. Everything else is normal down their just really itchy.

I know it’s not an std because I’ve been with the same man for 5 yrs and have been tested before we started dating and when I was pregnant. He’s also at home all the time so I know he’s not cheating.

Any hate will be deleted. I don’t have time for negativity. I’m calling the dr on Monday but any help/tips/advice would be welcome.
