Normal cycle length?

When I was on the pill for the past 8 years I had normal, 27 or 28 day, cycles. I finished my pack of BC at the end of July, had a normal period and then didn't continue with the next month. 25 days later I had another period. According to the app it was a few days early but I was like okay well this is good at least I'm having a normal cycle yay! Well since then, it is CD 35 for me and all BFN but technically am a week late for my period. I'm worried it's going to take a while to be normal, but I'm also wondering if maybe I'll just have longer cycles? So I'm curious to see what's normal for everyone else. My husband and I really want to keep TTC but it's hard when you are waiting and waiting for AF 🙄
