I'm 31 and I've been ttc for 4 years now. Everyone I know is getting pregnant. And I cry all the time wondering why not us. I have done Clomid for the past 9 months and nothing, fertility tracking, and my hubby has done a sperm count and he is fine. How do you know when enough is enough and it's time to give up? or am I letting my emotions getting the best of me?
