Does anyone else feel this way?

My husband and I have been ttc since December. I feel like ever since we started everywhere I turn someone is announcing their pregnancy! I am happy for everyone but inside I am so incredibly upset. Is this normal?? Just yesterday two couples that are good friends with my husband told us they were expecting! One couple has been trying for a while and I am very excited for them! The other couple is "dating" on and off and he called my husband to complain that she had a positive test! My husband doesn't understand why I am so upset!!! He keeps telling me it will happen and to stop thinking about it but I can't help but think about it and get upset when I hear all these other couples being successful!
