My husband is sad.

So this is our first month TTC. He thought I would just get pregnant right away. I keep trying to explain to him that on average couples don't get pregnant for 6 months to a year, sometimes longer. So I am 3 days to AF. I'm 85% sure I'm not pregnant. No signs of anything but the usual AF signs. So I told him this and he just almost cried. He wants a baby so bad and I do too but, I understand that it's not that easy. I don't know how to comfort him or make it any better. I don't know what to say. Any advice lady's cause I know this probably won't be the last month that I don't get pregnant. I'm hoping but I understand that it isn't that easy so I'm trying not to get my hopes up to much.
