Weird period?

Gi

I experienced a miscarriage at the end of June. Before being pregnant, my period was always on time so I’m just not sure what to think of it. My first period after came July 27th, then again two weeks later on August 17th. According to the app I SHOULD’VE started last Saturday. Can I expect for my periods to be irregular now?We’re not necessarily trying right this second because my body is still trying to get back to normal with other medical issues but my mom keeps teasing that I should test...I just don’t want to get my hopes up so quickly again.
