Barely Pregnant?

Well, the nurse called me back last night. She said that anything over 5 is considered pregnant and my levels are only slightly above that. So, she says that I'm barely pregnant. I'm still bleeding though, so I asked her if she really thought I was pregnant or if I was in the middle of miscarrying and she said there's no way to tell until I have the other blood test done and he wanted that done within 48 hours...so I'm going to go back Thursday morning to have it repeated. She said he'd want to schedule an appt with me after the blood test results came back in since I am a diabetic and that needs to be well-controlled throughout the pregnancy. I told her that right now I was too scared to even think that far. I'm scared...
