How embarrassing

I went to the hospital this morning because of my all over stomach pain since last night. I’m thinking since I had MC in the past that i may MC again. No blood work was ordered but a pregnancy test was and it was negative😫😫😫 I spent about $40 on FRER that says I am.. what is going on?! When I get home I’m calling first response for a refund.. these tests are misleading and embarrassing . That explains negative test on clearblue..Same thing happened yesterday when I went to Dr’s office.. I’m officially done with FRER‼️
