Late period

Hi! Wanted to get some opinions on this here. I had back to back IUI’s that failed. Then skipped this past month and would try naturally. Went AF didn’t come on her normal time, i started to get excited as i have never been someone that has ever been late. Well here i am 5 days late and AF decided to come in full force.

Anyone else have this same situation? Anyone know why i would have started this late?!

My stress levels are the same as they have been and I’ve normally been on a 29 day cycle every month 30 max but rare.

Thanks in advance!
