Positive vibes!

I am ttc. My expected period is on Thursday. Today I experienced some cramping. Kinda hurt, like a dull pain. Just got out the shower & had some white discharge. Kind of sticky & stringy between my fingers. I google everything & I go right back to early pregnancy!! My boobs dont feel different but I think, not sure. But the area around my nipple looks a little darker then I remember. But I could be jinxing myself. I need positive vibes!!
