Pregnant after husband had affair

I just found out I'm pregnant (insert butterflies and excitement here) and I'm over the moon. My husband and I have been together for four years and have a 16 month old son. A few months ago, I discovered my husband was having an affair while he was living in a different state temporarily due to his military service. The affair didn't last long, and this is the first time that anything like this has ever happened. I was shattered, but also had to keep it together for our son. Am I crazy for this pregnancy? It feels right, and I have faith that my husband and I can move forward to a healthy relationship and life.
