Pinkish discharge with cramps

So yesterday I felt very nauseous around the evening time and later on that night my nipples were sore and itchy, the next day I started have period like cramps in the morning and I’m still having it when I went to use the bathroom and I wipe I had a pinkish discharge but my period comes on in 8 days, and I have a regular period. Is this normal, do you guys think I may be pregnant?
