What should I do I'm feeling so broody already?

I gave birth for the first time 4 weeks ago but I am feeling broody again. I feel like I want another child but our plan wasn't to have another one till this baby was 5 years old!! I don't think I will last lol. How can I divert these feelings and why am I feeling this way when I was screaming I WILL NEVER HAVE ANOTHER BABY KILL ME NOW, in labor!??
