Am I going crazy? What is wrong with my brain?!

My husband and I haven't even started TTC yet (though we weren't NOT trying last month and plan on actively trying next month). But for some reason I am overcome with jealousy every time I see or hear about a pregnant person!

My husband's cousin just Facetimed us to announce their pregnancy. They are lovely people. I should be happy for them! Why am I so jealous?! I have no right to be jealous! We haven't really even tried yet! There are people who try for years -- they have a right to be jealous. What is wrong with me?
