AF after miscarriage HELP!

Hope you're all doing well.

I had a blighted ovum around April this year. I got my periods 5 weeks after that. The first cycle was 35 days, then it went on to 32 days and this time I was expecting it to be about 28-30 days. It's now 33 days and I still haven't gotten my AF. I don't understand what's going on.

I have been checking my cervix and it's firm, medium height and closed.

Now, I haven't checked for pregnancy yet. I think it could still be too early to check. Plus am a bit scared to check as I don't want to be disappointed, as am sure most if ya'll have experienced.

Am just wondering is it normal for AF to go back to a 35 day cycle?

Plzzz help!

Thanks ❤️❤️❤️❤️❤️❤️
