My husband is pregnant

My husband has been so caring and attentive so far in my pregnancy. I love him for it but today I am convinced that my husband is the one who's pregnant. I've never been so mellow in my life. Meanwhile this guy is so unusually moody lol. I can barely eat and he ordered two tacos at Taco Bell and made an unnecessary stop for fries and milkshake at mcdonalds..just for him. What is going on with him? Is mine the only one?
