Cycle is changing?

☣X

I'm 20 years old, and I've had my period for 8 years now. It only took like 2 years for it to regulate, and the last 6 years I've been blessed with a 24 day cycle that is so regular I could almost pinpoint the hour it was supposed to start 😂❤

Of course, maybe it was too good to be true. My last two cycles were suddenly 28 day cycles. The first time I was convinced I was pregnant, although the 10 tests I took were all negative lmao.

I was sure I'd go back to my normal 24, but again I just finished a 28 day cycle. It's totally messing with my head since I'm always really regular and haven't had anything other than a 24 day cycle in 6 years.

I was on the Kyleena IUD a few years ago, and my cycle didn't change at all. Even after I had it taken out last year everything was still normal. I haven't been on any birth control other than that and we've just been using condoms.

I can't really think of any reasons why my cycle might be changing like it is. I know stress and diet can be a factor, but I'm sure that I'm doing nothing different. I know my cycle is still very much within the realm of "Normal" and that's reassuring, but since it's not normal for ME if I should see my obgyn or not? Thoughts?
