Heartbroken, not pregnant

While my husband and I aren’t TTC, we both got excited when my period was 7 days late this month. There had been one instance while I was ovulating that we didn’t use protection. My period came this morning and I’m just devastated. My husband is amazingly supportive and I love him more than anything, second only to The Lord, but there is something that feels so lonely about having physically been the one who’d gone through it. The only thing giving me true comfort is knowing that this is God’s plan for us, whatever it is. Anyone ever felt this alone?
