Creamy CM

Kate • 32. Canadian. TTC #1 since Aug. 2014. PCOS. Endometriosis. MC in June 2016. Uterine septum removed January 2017.
Some ladies have been saying that they have creamy CM before getting their BFP
My question is, do you HAVE to have creamy CM in order to get a BFP, or have any of you had different CM before you got your BFP?
