Am I being unreasonable?

Sorry long post!!!

Just wanting some thoughts from people outside of the situation. My husbands family is from California. His sister and her son are moving to the state we live in. No one in his family has been following any sort of recommended guidelines as far as protecting themselves or other people from covid 19. My husband tells me with less than 24 hours notice that his sister and nephew will be coming and staying in our house until they can move into their new house. I’m 22 weeks pregnant, and we have an almost 2 year old daughter. My family has been very strict when it comes to following guidelines (My daughter nor I have been into a public place except for my doctor appointments since the beginning of March, my husband only goes out for essentials and always wears a mask, we practice social distancing). I told my husband I was extremely uncomfortable with his sister and her son staying in our home with the current coronavirus situation (cases on the rise, they traveled by plane, stopped at 3 airports, do not follow guidelines), and I would rather them get a hotel for the 2-3 days before they can move into their house, because I do not want to potentially expose my daughter or myself (and our growing baby) to this virus. His family, including his mom, basically said screw you we are staying anyways, and have been at my house for the last 3 days. So my daughter and I left our home to stay with my parents (who have also been very strict with following guidelines) to allow them to stay in our home, and avoid any potential exposure. I feel EXTREMELY disrespected by his family. I feel that they completely dismissed my feelings, and what I want for my child. Not only that, but I work a full time job (from home) and had to move all of my equipment to my parents house that is not set up for me to work from home with my 23 month old. Am I wrong to be upset and feel disrespected by this?
