proof of pregnancy!

I've been running around like crazy trying to get proof of pregnancy an it seems like its impossible! I've been to every health department an none will give me proof of pregnancy until next week. an until I get it my insurance wont cover anything pregnancy sp I have the choice of waiting next week to get proof an up to 4weeks for my insurance to kick in. or pay 30$ for bc a pregnancy test at the obgyn!!! why is this so freaking hard!!!! also according to the app I'm 10weeks🤦🏼‍♀️🤦🏼‍♀️🤦🏼‍♀️
