so confused

Felicia
last Sunday July 3 I took a hpt, it came back positive that night I started to spot so I went for tues day for blood since Monday was a holiday... my hgc was at 31 and my progesterone was at 1 ..I swore I was having a miscarriage since I was bleeding... I went back Thursday to Make sure everything came out and my levels dropped to normal... here my hcg went from 31-66 and my progesterone 1 - 3.9 ..they put me on progesterone suppositories 2 times a day... my question is could this still be a viable pregnancy? I'm so confused I thought I had a miscarriage. does anyone have any similar stories and had a positive outcome.. I go for more blood on Sat morning... the bottom was from last night . also I just stopped bleeding
