Question - Length of Cycle

I will be 38 this summer, For past 1 year my cycle lengths are gradually increasing like it was 26 day cycle , July - Dec 2020 it was 28 days and since Jan 2021 , it is 29-30 days cycle ...

I did change my diet for past 6 months and also started doing breathing exercises daily.

On the other hand I am seriously concerned if am getting my closure to early menopause as we don’t have have any kids and trying to conceive .. sincere Thanks in advance for all your insights ...
