How do I know if I have an irregular period?
An irregular period, to me, would be a cycle that is shorter than 27 days or longer than 38 days. The other definition could be if your time between each cycle varies more than 7-9 days, meaning one cycle is 27 days and then your next cycle, or the length of time you have to wait to get your next period, is 42 days, and that’s consistently happening over 3 months. That, to me, is an irregular period. I have patients who come in who have had [an irregular period] over two cycles, but they’ve also traveled a lot, they were sick a month ago, they have jet lag, they’ve been training for a marathon – all of those things can definitely give you an irregular period. Again, it’s more consistency over time that would make me worry.
