Late Period

Hey all,

I’m looking for some help with late periods and it’s not due to pregnancy. I have a pretty regular period and I’m not on birth control. I have been late to start for about two weeks now. In the past 12 years that I’ve had a period, I’ve never been over a week late and I attributed it to stress when it happened in the past. This time it’s longer and I’m wondering if I should be concerned? Any thoughts?
