Pregnancy cramps or period?

I have been cramping since Thursday and my period isn’t due Monday- Wednesday. The cramps have been on both sides and the middle but none of them have been bad. They feel like light period cramps to me. And last night, after sleeping all day, my breasts were randomly so sore that they felt bruised or like how your legs feel after leg day lol. But my breast were hurting when I touched them, walked bra-less and did anything to expand my chest like deep breaths and arm stretches.

I had an orgasm yesterday and I swear I saw a little tinge of pink/brown when I wiped after.

I guess my question is could these somehow be pregnancy cramps? Where do you feel pregnancy cramps? What do they feel like?
