yes, you can even just skip this cycle entirely. Your hormones were perhaps disrupted during ovulation, and you can simply skip this ovulation and be right back on track next month. If you skip another cycle, then see a doctor. In college I skipped 3 months, was not pregnant, and was put on the pill to even out my cycles. There are also pregnancy tests now that are so sensitive they can check for pregnancy pretty much right after missing your period.
