cramping 4 days early.

Holly

so I took a FRER pregnancy test 8DPO and it was neg. now I am 10DPO, AF due on either Saturday or sunday.. I have been having what feels like light cramps since before noon today like my period is coming but it hasn't. I was 2 days early last month... usually 30-32 day cycle. I keep expecting to go to the bathroom and have AF be there but nothing. very light creamy CM but barely at all... anyone else find this happening to them? or before they got their BFP. I'm afraid to take another test too early again and be disappointed. . .
