Can I wear Spanx???

I am 6w and 5 days today but my first US isn't until November 8th 😩. I had a MC in April so I'm waiting until after the US to actually tell anyone.. (The only one who knows is my SO I haven't even told my mother or sister!) I have a wedding this weekend (all my family and friends) and this bloat is way out of control lol I for sure don't want anyone to know that I am pregnant yet until I go for my US and know everything is okay. I went through having to tell everyone I lost the baby before and God forbid don't want to have to do it again... Is it safe for me to wear Spanx for the wedding? Lol I'm sure it will be uncomfortable but I def don't want to hurt the baby. Thanks!
