losing my mind

We just found out and it says I'm 4 weeks and 1 day... However since I had a MC Nov 2016, I'm freaking out about this. Every little pain I feel I start to think it's happening again. My doctor appt isn't until the 14th. The pain comes and goes, however sometimes I feel it in my legs for a short period of time. I just want to be at ease. Hard to be excited when you experienced the loss before.
