Has anyone heard of S/o getting sick when girlfriend is pregnant?

We just found out I was pregnant last night.... and this morning we went to eat with my parents and my boyfriend got sick.. My mom said that he got sick because I was pregnant and he was taking the symptoms. 😂🤦🏽‍♀️ I thought she was just playing because my dad didn’t know yet and she did. But later when we told my s/o mother she also said he was sick because IM PREGNANT. I am, but here’s my question, is this a real thing ? Or is my boyfriend just sick 😂
