Need Help ASAP

Lovingly

My period doesn’t start for another 2 weeks I am cramping and when I wiped i saw pink on the tissue. Now every time I wipe that’s what I see. It’s not dark and it’s not a lot. I do have discharged that’s clear and watery. I took a pregnancy test and it was negative. So do you ladies and any inclination of what could be going on? Thanks in advance.
