Some normally regular women occasionally skip a cycle or two. This is often attributed to a cycle when an egg is not released. The lack of ovulation cancels part of the hormone production that allows breakdown of endometrial tissue/menses. When the menses is delayed by this factor it is often longer with more flow from excess estrogen buildup. The pattern is not indicative of pregnancy.
