If CM dries up after ovulation does that mean no possible chance of pregnancy?

I posted this late last night and didn't get any responses so I thought I would try again. I normally don't dry up right away after ovulation. In fact I normally have a lot of the lotion like CM that surrounds my cervix. Well this month I dried up the day after ovulation and there is no lotion like CM around my cervix like every other month. I asked a fellow ttcer and she said that it means I didn't conceive this month? So I was wondering did anyone dry up after ovulation and get a BFP later in the month? Or should I just figure that this month is not an option. I had on Saturday Jan. 10th, Sunday Jan. 11th, and I ovulated on Monday. I know there is no way I could have any symptoms or anything like that so this isn't one of those questions. I was just wondering about cervical mucus changes.
