Dry cm throughout cycle???

Ladies so normally I go through the cm "phases" and "dry up" right before Af. This is what normally happens when I don't conceive. Well I have been monitorin my cm the past few months and believe that I "o" early. Like within the week following my period. So that's what I went off of for this cycle and since we "DDT" around (what I would say is my) "o" day I have been dry. This is not normal for me. Is it possible I may be pregnant?  I know normally a woman does not dry up if she conceived but I'm confused...
