My worst fear

Sophia • Hi my name is Sophia and my husband and I just got married on April 23rd 2015:)
I'm feeling so discouraged lately, every month u hope to be pregnant then u start your period:( my worst fear is never being able to give my husband a child. We haven't been trying for long but i don't see what the problem is. It's not to compare myself to other woman, and it's hard to stay positive
