Have you ever missed your period by a whole month?

If yes, did you get it again after that missed month? I am 20, and I got my first period at 13. Ever since I was 13 I’ve had constant periods. Always on time, every month, no issues. But I am 25 days late & I am confused. I don’t have insurance to go to a doctor right now & I’m a full time student with a job so it’s kind of hard to make time either way

Has this happened to anyone? Yes I am stressed, but I’ve been way more stressed before and I still always get my period. I know you aren’t doctors...but anyone who can relate, what was it for you?
