Oh I am going through the sort of thing at the moment. I am pretty sure I Ov on 1 Aug (we BD the night before) as I had a big globby CM come out (it wasnt DH stuff either, um sorry if TMI) which was watery and should be the usual fertile CM and today I have had that watery CM like u have mentioned (and Im finding odd also)?? I must admit though, I have had other creamy type CM since Ov, so im very confused also.
