Am I overreacting?

Margo
My husband and I have been TTC for about 8 months now, no luck. He has a brother who has 2 kids already. Today, we went shopping and he keeps showing me baby clothes etc.. and I get really sad. He doesn't understand that if makes me sad. Every time AF shows up, I cried and he doesn't care. He just keeps telling me to stop being a baby. I don't think I'm overreacting honestly, but do you think I am?
