DH and I got a test from Walgreens. It is called Pre Conceive Plus Home Diagnostic Screening Male Fertility Test. That is what it says on the box. It is about 6 inches tall and 2 1/2 inches wide. Purple on the bottom and white on the top with purple writing on the box. There is a website listed on the box:

I think it was about $30 but it beats the $100 for a SA in the lab, especially if you are just trying to get an idea! My DH was the same way... he thought it was him. We found out later it was my eggs, they weren't maturing. I too was having irregular periods. Obviously seeing an RE is a good idea but you probably already know that! Good luck to you!
*Edited to add- The link doesn't take you where I thought it would! It takes you to the Pre-Seed website. But the one on the box is PreConceivePlus with a www at the beginning and a .com afterwards. (I guess you have to outsmart the system!)
