I can’t touch my nipples

It’s been going on for a few weeks now, my nipples are so sore, I can barely touch them without being in pain. I thought it was a pms thing, but it’s been weeks, my period is supposed to be here next week, but I’m nervous that I might not get it. If I miss it, should I test?

Ps, that’s not the only thing I was experiencing, my lower stomach has been cramping on and off, I just usually ignore it cause I’m lactose intolerant… but I cut out dairy to see if it would go away… help🥲
