How to prevent discouragement

So my husband and I have only been "trying" (off birth control) since December but I already feel discouraged that it hasn't happened. I started my period yesterday. But the first 2 months we weren't seriously trying we were just seeing what happened. I have 2 babies coming soon in my family and I keep wanting it to be me next...it hasn't even been that long we've been trying! What are things everyone follows to not feel discouraged month to month?
