Nervous...please help

Jessica

Hey guys so I'm 5-6 weeks along and I woke up this morning simply just not feeling pregnant...

I don't know if that's a bad sign but my boobs aren't sore, no morning sickness, not tired...

I'm really worried about having a miscarriage. I haven't had any cramping or bleeding but is this normal or did this happen to anyone else before miscarrying?

I go to my Dr. this Thursday but she doesn't want to do an ultrasound until the 21st....
