Idk what you would call something like this. In June my family dr did a blood test and said I was really close to the number that would say I'm pregnant so they told me there was a really good chance. And then I set up an appointment with an OBGYN and they did an ultrasound and nothing showed up. The OBGYN doesn't even know what to call it. Any ideas?
