Period every other month

Kassidy

Does anybody know some reasons why I get my period only every other month now (meant to post this on the period chat but I suppose I accidentally clicked the wrong group) however I used to have a semi regular period before my period would only skip one month and then I’d have it normal and then it would skip one month again but starting in April where I got my period in may I didn’t then I got it in June and July I didn’t get it
