Anyone ever get slimy tinted yellow cm before BFP?

Just curious! I'm 3 days until af, been cramping mainly in my ovaries. Its not a typical cramp like I get when af is 1 day away or actually here. Its been radiating in little spots all over my pelvic area. Today I found that cm that was slimy, clear but tinged with yellow. haven't had any since that, 6 hours ago.
