Okay so my period is 16 days late and I had some weird cervical mucus so I went to see my doctor today for a blood test.
I'm also a diabetic and she prescribed my insulin, which I haven't received yet because "the doctor didn't put a dosage". I mentioned this to her and she checked my history. The diabetic doctor put "cannot prescribe abasaglar because pt is pregnant". 
So now I'm freaking out, by my calculations, if I am pregnant I am about 4-5 weeks gone. 
After endless negative tests could this be the light at the end of the tunnel?
