TMI - does this happen to anyone else?

Gr

This is tmi but whenever you’re on your period (around day 3 or 4 for me) does your vagina ever get like sore? I don’t know how else to describe it other than that, like tired and sore lol. I only ever have that during my period and I’m having it today (not sure how many dpo because I don’t know when exactly I ovulated as I had several positive opks - around 4-6dpo I think) with there still being 11 days until my period. Does this ever happen to anyone and could this be a sign of pregnancy?
