Am i a bad person?

Bonnie
Right well me and my SO have been together for 4 year and been TTC for 6 months and his brother has just had a baby with his girlfriend and they were only together a month when she found out she was pregnant and split up so many times during the pregnancy i feel like a bad person because i just feel jealous of how easy it is for some people dont get me wrong their baby is adorable and theyre good parents. I guess it just hurts that people who arent in a proper relationship ended up with an unplanned pregancy in the blink of an eye but yet people who are actually trying it takes so long anyone else feel like this or just me ?
