20 day cycle?

[birthdayblues31]

The past few months, my periods have been weird. 2 months ago, I had a crazy heavy one, followed by a normal one 25 days later and now on again on day 21. I'm 31, not on any hormonal contraceptives, always been pretty average/regular. I temp and had a big temp drop today so definitely my period but should I be concerned it's so early? I've tracked religiously for 2.5 years and cycles have always been 23-27 days but 90% 25 days.

If it's just one off I wouldn't worry. Its only slightly shorter than your shortest so far, it's not really beyond the realms of normal. If you suddenly had like a few in a row then maybe see the GP but otherwise wouldn't worry. Bodies do random things all the time.

Thanks @MeadowHay. Bloody health anxiety reigning again.
