Problems TTC!!!!

I'm 22 years old and my boyfriend and I have been together for 4 years. We've been TTC for a little over 2 years and now I'm beginning to become frustrated and just give up. I often feel discouraged because I'm only 22 and my OB/GYN says I shouldn't have any issues TTC. I'm reaching out because I want to see if anyone else has had these issues. And also to gain some emotional support.
