has anyone ever went back to being irregular?

I had a miscarriage back in February of this year before my miscarriage I was very irregular to point I didn't even know I was pregnant after my miscarriage I became regular every month since then I have had my period and I have been logging all my info on my apps. hoping and praying every month I get pregnant. well it's now November and AF was due almost a week ago and I am praying my little bundle is finally here so I just wanted to know if it is possible to goo back to being irregular
