Ladies please help! I need advice :(

I'm so torn. My MIL is throwing a party on Thursday for my SIL, SILs bestie and the besties girlfriend. The 3 are all flying in from Spain tomorrow. She is inviting around 10+ other people, plus my family so its a total of over 20+ people. There may be even more, it seems like she's really going all out. Its outdoors but in a small area.

My concern is I know no one will be wearing masks. I have no clue who these other people have been in contact with. I have 12 to 13 weeks until baby is due. What if someone is sick with Corona and I catch it. What if I go into early labor (my 1st came early at 35 weeks, my 2nd at 36 weeks)? I don't want to potentially be separated from my baby especially if born early Im sure they would be extra cautious, or what if my husband got sick and couldn't be there for the delivery. Im obviously thinking the worst case scenario but shit happens, you never know! The cases in our county have been rising ever sense they reopened stores :/

I've discussed my concerns to my husband and he still wants to go witch is odd because hes been paranoid going to work and making everyone who enters his store wear a mask!!! I feel so uneasy, its giving me anxiety. I can either go and try to keep my distance from people, Im kinda anti social and tend to sit away in normal circumstances. Or I can just stay home with my toddler. Im leaning towards staying home, or maybe taking my own car and assessing the situation and if I get too worried I can just leave. Im supposed to bring a cake so I could go drop it off say hi and get the hell out....

Please be honest, what would you guys do?

My MIL will definitely be offended if me and toddler don't show 😒 😤 😑
