waiting on second hcg test

Hi ladies...I had a chemical pregnancy early in January and just found out I am pregnant. Unfortunately with the chemical miscarriage I never got my period last month and have no idea when I ovulated. I was shocked to start getting breast tenderness again so soon but took a test and it was positive! I went to my doc last wed. for blood work and my hcg was only 88 meaning either I'm very early or I'm having another miscarriage. I had my blood taken again Friday and have had to wait till Monday (tomorrow) to find out my results. I'm so scared and nervous. Has anyone else gone through this?
