Nervous

Cate • First time mommy due 11/8/16 with our precious baby boy Logan James
I am 7w5d. We just told my mom yesterday, and while she was really excited, she also reminded me that women in our family have a history of miscarriage with a first pregnancy. We have not been to the doctor yet to confirm a heartbeat (appt 4/14) and I am now just so scared that something is wrong. I have not had any spotting (knock on wood!)...
Am I being paranoid? Should I try to get in to the doctor earlier?
