Is this a normal thing for a mom to say?

I was going to attend a family bbq this weekend but I canceled bc I found out someone who’s going may have Covid. I’m pregnant and don’t want to risk getting sick. My husband is going upstate to his family’s house for his moms bday & Mother’s Day, with just his parents. I love going to his upstate house and go there often but wasn’t planning to go this weekend, I need to stay home and study. When I called my mom to tell her I’m not going to the bbq anymore, she said (in a very stern voice) that if I wasn’t going to my family’s bbq anymore, she would be very upset if I go with my husband upstate instead and don’t see her at all over the weekend for Mother’s Day. Implying that it would be a very big deal and she’d be mad at me.

I made a plan to see my mom Sunday morning for breakfast so all is good now, but was that a normal thing for a mom to say to her 28 year old daughter? My husband thought it was kind of harsh and unhealthy, like she was saying I should sacrifice any chance of me having a good weekend just to go visit her for a few hours for this ‘holiday’.
