High LH Levels

Allison • 26. Married. #1 due 7/16/17!
I haven't had a period since February of this year so my primary doctor did some blood work to see what's up. 
All of my hormones came back normal except my LH levels which, as the nurse put it, are similar to that of a post-menopausal woman. A.K.A super high. 
I'm scheduled to go in for an ultrasound tomorrow morning and then have an appointment with an OB tomorrow afternoon.
Has anyone else had this problem with only LH levels? Any advice or stories? I'd love to hear.
