Better CM in morning?

[psychochick]

I've noticed the last few cycles that when I check my CM in the morning of fertile week, it's EWCM, but if we BD at night, at that time when I check CM, it's no longer EWCM. Does anyone else have the same experience? Does that mean we should BD in the mornings? It's not always possible because of work schedules and I kind of thought if I had EWCM in the morning, it means that I should be fertile that evening too, but now I think maybe in the evening my body's more tired and doesn't create enough CM to be fertile
