Looking for some AF advise

So

So...ladies.

I have a 31-34 day cycle. Since coming off the pill and TTC since June 17 I’ve not fallen pregnant I’m nor have a every really been late for AF.

This month I am now 5 days late. No sign of AF at all.

I’m not overly stressed and I’ve taken many, many, many tests and not pregnant it appears.

Any ideas what could be going on/ what to do?

Thank 😘😘😘
