Relax and it will happen

Anyone get tired of hearing relax and it will happen? My doctor told me this today. I kinda think it's a crock of #%$#. Sure, if you are severely stressed your body would stop ovulating, but if you are getting positive opks, stress shouldn't be the issue. I asked for a referral for an hsg. Ahe really didn't want to give it to me because of her insurance agreement. (I haven't been trying for a year) I've been stressing over it because I've had chlamydia that went undiagnosed for a few months and I need to know if I'm affected or I will continue to stress for the entirety of my TTC journey. So do you think the stop worrying and it it will happen is just a phrase people say?
