Hi everyone - hoping someone can help.......

Is it normal to have delayed AF post failed OI and IUI cycle?

We did a down reg IUI cycle which ended with (BFN) and AF arrived on the 22nd Dec. I am still waiting for my next AF to start an IVF cycle but i'm now CD 44??????????
1. I'm not prgnant as have neg HPT
2. I have a history of irreg periods but at most 39 days, never had anything longer?

Just wondering if anyone has had the same? We will be doing our first antagonist IVF cycle commencing puregon CD2 so i'm waiting waiting!!!
