Uhm, what is this????

Katelyn • Endo Warrior 💛 working towards baby #1.
My af is due on the 30th. Today I wiped and there was a pinkish discharge. Now I guess I'm spotting or bleeding very very lightly and I'm getting some cramps. Please don't be my af early :/ I need to add that it is brown/dark red, not like blood red.
