Please look at CM in pic... CD 31 no period

FM • 34 yo- TTC since Oct. 2012. Endometriosis And 9cm Fibroid excised in Oct. 2015.
Sorry for this gross pic but I am on CD 31 no period and this is the only sign of it I have had so far that makes me think AF may be on her way.  I had so much EWCM this morning which isn't normal for me.  Normally I have my period by CD 29 at the latest.  Praying for a miracle ... What do you think? Could this still be a BFP
