Am I being too cautious

Just wanting a little advice.

I am pregnant, I am also invited to a engagement party on the weekend with around 100 ppl attending. I have been avoiding large get togethers because of covid. I know that it's now with omicron considered pretty mild if I do get it. Friends are now starting to roll there eyes at me when I say why I am avoiding large groups of ppl. I totally agree with life continuing like normal. Just wanting to be cautious since I am pregnant and when I have a young child and new born. I am fully vaccinated and I also have a 1year old at home.

Should I loosen up a little?
