Losing my rainbow baby?

Kaitlynn
According to my LMP I am 7 weeks today. This week I had some brown spotting and went and had blood work down yesterday. They said my hgc was 119 and said it should be over 2,000. I got back Monday to do blood work again. So I'm assuming I'm having another miscarriage. That will be 2 for 2. I feel as though somthing is wrong with me losing both of my pregnancies like this. Anybody else had low levels and still went on to have a healthy baby? Should I go back on birth control and give up since my body keeps doing this? I just can't believe I'm doing this again.
