Took an ovulation test today/other questions I have!

So glow said today should be my fertile day and to take an ovulation test and so I did and I want fertile. I had a clear circle, no happy face! 😞 I'm hoping tomorrow it will change. Has anyone had that happen to you? 
My husband and I have been trying for 8 months now and nothing. I've gone to the doctors to get check to make sure I'm okay, he wanted to test me for PCOS and I'm clear from that. He did say that I should go see a fertility doctor and see what he says about everything. (My doctor/gyn Doctor) told me I might need a "boost of hormone shot". (Not too sure what name of the shot was) Who has been successful with getting the shot and it working? Please any advice would be very much appreciated! 
Thanks!!!! 😌
