Husband has morning sickness😳🤔

Is this a thing? Has it happened to your husband too? I'm 7 weeks. Haven't actually had morning sickness myself just nousea. He came home from work bc he was throwing up and his head hurts. He barely ever gets sick. Is this just a coincidence ? Lol 
My mom said my dad got "morning sickness" a week after she had it and she was feeling great lmao!
