Cycle confusion!

Brittany

I have been off of birth control for a little over a month now and also have an 8 month old(yes we want another baby already) before baby and birth control I had 28-30 day cycles. I just started tracking periods last month and My period was June 14th and I’m now currently on which started July 19th. That puts me at a 34-35 day cycle which is new to me. So, would ovulation be around day 17 based off that cycle? I’m afraid I will miss my fertile window if that was just a fluke and my body decides to go back to having 28-30 day cycles.
