This is so frustrating

So my SO and I have been trying for about 5 months now. We started on a supplement known as Conception about a month in. No such luck there. So I started using OPKs and pre-seed to make sure that the sperm should be able to reach my egg. I am teetering on what we should do next because my SO says that he wants to get his count tested and I want to start seeing a fertility specialist but I am terrified that I'll be told that I can't have kids! Yes I know there are other options but it has always been a dream of both of ours to have at least a couple genetic kids. Ya know? And it's so frustrating to try not to stress about it and we've been trying not to focus too much on it but still track my cycles 🙄🙄 if anyone has advice it would be much appreciated!
