Ovulation after cycle of IVF

Hi ladies so a quick run down,

I did my first IVF cycle last month was suppose to have fresh transfer on the 1st of April but neither of our 2 Embryos made it to day 5, and then as we all know IVF was put on hold so i have just been winging it naturally this month, long story short im now on CD22 and still no positive opk i usually get Them anywhere from CD 15-21, I have been testing 2-3 times a day since CD12 and nothing, has anybody had the same experience, Ovulated later or not at all?

Have a follow up appointment on the 8th of May as we have been given the green light to start IVF again i was due for AF on the 10th so it worked out well but now im worried it will be delayed alot or i may go back to not ovualtion at all so no AF 😪🤦🏼‍♀️
