Waiting for 3rd Beta

I'm waiting to have my beta level drawn again tomorrow and then results on Monday.  Let me tell you, it feels like a long time to wait!  In the mean time, I have been working on seriously chilling the f*** out.  I feel like I'm in this limbo:  wanting to be really excited, but also fearing miscarriage.  However, I can't spend 12 weeks like this.  What's going to happen, is going to happen.  Other than just taking good care of my body, I can't really do much else.  It's out of my control.  I have looked forward to being pregnant for a long time, so I am basically trying to look at each day as "I'm still pregnant today."
