I'm usually pretty regular with my menstrual cycle, like 30 to 32 days. But this month, I'm 18 days late, and I'm not sure why. I've done both urine and blood pregnancy tests, and they're negative. I'm not stressed or on any meds, so I'm really confused about what's going on. Any ideas on what might be causing this? What should I do next?
