Ariel
Hi ladies!  I'll be 7 weeks tomorrow, FTM!  I am wondering if anyone else ever has symptoms that Coke and
Go?  Some days I have awful ready pain, and others they feel almos normal!  I defection comes and goes, etc.  
This is really worrying me, I've miscarried before but didn't experience this.  Anyone else??
Thanks in advance!
