May 18th anyone???

I got my BFP 9/9, and I went and had a blood test done. They called back and said I was at 65 HCG. Everyone else's HCG levels on here are crazy high! I was about 3 weeks 6 days when I went in and my period was supposed to start this coming Monday. The low level is freaking me out when I see everyone else's.... Light cramping, but nothing like period cramping. Anyone else out there due around this time having the same HCG/symptoms??
