CM question TMI..

Ashley
I have only been ttc for a month currently 7dpo and I have very large amounts of creamy white cm and have for 3-4 days I have read that can come before a period however I have never had it before. For those who have gotten a BFP and tracked cm did yours go from EW to watery to creamy? I have heard of this happening just wondered how many women really get this type of cm before a BFP.
