Cramps in anus?!

Kristen • Mama to one boy born May 2019 - currently TTC baby #2, wish us luck 😍

Sometimes at the very beginning of my period I experience sharp pains/cramps in my anus area. It almost feels like rectal spasms and can be extremely painful and uncontrollable. It comes in waves and only lasts a few seconds at a time. Then my normal period cramps will start in my lower abdomen soon after.

Does anyone else experience this sort of cramping? Should I be worried? 😥😣
