Down in the dumps

My friend just called and told me hima nd his gf are pregnant. And while I'm happy for him I can't help but feel extreme jealousy. He is about to turn 25 and just lost his virginity a couple months ago. They wernt even really trying they were just "seeing what happens" while me and my husband are trying so hard. He's freaking out. I really am excited for hI'm but I feel like I'm losing hope. I want to be pregnant so bad :(
