Hcg 4....

Tori • Baby Kinlee due 12/17.
So 3 days ago I got a positive frer followed by 2 more. They were faint And the dr called me back saying my levels were 4. So I decided to test again with a walmart test and it was negative. The dr said I might not be far along enough yet but my of was due yesterday.... He said to test again in a week. I have no bleeding and slight cramps. I have no idea what is going on. I had a mc in September and in pretty sure this is a cp. Idk how to keep hope at this point.
