5 months too soon

Hi ladies. I write this during an internal battle that has me broken. My baby girl is 9 months july 15. I just found out I am pregnant around 4 weeks. We definitely want another baby but not until our girl is at least a year old. I also had a c section with her and need to let my uterus heal. This is too soon for me, 5 months too soon. My immediate reaction was fear and stress and tears. This isn’t what this moment should feel like... right?! Am I being selfish? what if i don’t get pregnant again.... Please help me 😢
