Getting discouraged too soon

We are currently in month 3 of ttc and I'm getting way to down about it not happening. This will be his 1st and my 2nd. The 1st time my ex and I ttc it was extremely easy. Now that was over 8yrs though. Im 28 and he is 29. I am starting to wonder if he has fertility concerns or if I have acquired fertility issues over the last 8yrs. Af is due to make an appearance in about 8 days and I really hope she doesn't make an appearance.
