Pregnant husband?

I am happily married to my wife of three years. Our marriage has been good with the usual ups and downs but there hasn’t been anything we couldn’t handle. My wife is currently pregnant and the first trimester was a little tough for her. This second trimester is going well with no complications whatsoever and I’m very grateful for all of it.

I, however, noticed something rather peculiar the other day. I’m suddenly having cravings, backaches, nausea, and other symptoms that are very similar to pregnancy while my wife seems fine. The doctor says my health is perfect. Do men experience these things too?
