Help what are we doing wrong!!!!!

My name is Dolly my boyfriend and I have been trying to conceive for over three years and we haven't had any luck. My boyfriend went to a specialist at Geisinger to have himself checked out and the results were OK but his protein was very low but sperm count was normal. Is there anyway that I could suggest to him about protein or what he needs to do to up his protein levels? I have also went to many examinations for my irregular periods and been on Clomid Metformin and progesterone.  I've had irregular periods for a while so I was put on birth control to regulate them but now I am not on birth control(haven't been for a few months maybe like 4 or 5) but my period comes once a month regularly and I'm starting  to realize when I  think I'm ovulating and when I don't and I've been using this app to help me but each month I get a big fat negative are there any suggestions from my glow community on how to conceive any help would be much appreciated. Thank you and good luck to all that are trying!!!
