This is a long cycle

Today is CD 28. This is one of the longest cycles I have had in a while. Usually my period arrives like 4 days ago. However this was a wacky cycle. If I did ovulate it was on CD 18 which is 2 days later than last cycle. So that puts me at 10 dpo which is 1 day longer than last cycle. I am giving it until Saturday to test only because husband is going out of town Sunday.
