Second beta and terrified

We'll last night I had the smallest amount of spotting once I got to bed.  I was sure it was the end of things and AF had arrived.  I still thought it was too early and at least I was right about that.  This morning I just had a littl brown spotting the first time and since then it's gone.
You have to understand that because I wanted to test before I saw my RE on Thursday, I tested on what I think was CD22.  I wasn't even expecting to see a positive at that point except that I was feeling pregnant. Turns out my beta was 9.  Yes ladies 9 ! The nurse told me that since I had tested so early she wasn't really surprised and that I was in the good range for CD22 and I just needed to wait for my 2nd beta.
I POAS again this morning and it's still positive.  I just can't tell if the line is getting any darker or not and lets not forget today would still only be CD24 !
I hate this cause I never test this early.  I might be the POAS Queen but I still usually wait until the day AF is suppose to show. My cycle is 26 days.
I'm scared but I've decided I need to stay positive.  I refuse to give up on this baby ! I soooo want this pregnancy to work out I've decided I will will it to work.
I'll update once I have my new beta number.
