Hcg levels. Ugh!!!!

I'm not sure if I like knowing my levels and then stressing about them or if I wish I didn't know so much information and just sat back and enjoyed being pregnant. I MC last February due to low progesterone and hcg levels not going up. I tried to not stress last month about TTC and didn't use opks so now I have no idea when I ovulated. 9 days ago my levels were only 51 and as of yesterday they are 816. My dr seems fine with them but I want to cry. I go back AGAIN tomorrow to see if they're still rising.
