Why am I sooo broodie

el
I have a beautiful 5month old son but from the minuet I had him I have been so up for it with my partner and broodie It's unreal I couldn't even wait 6 weeks for us to get down to it so we waited 3 weeks after me having my son so I had healed properly from my epsoptomy. 
I keep hoping my hormones will calm down as I can only just manage my one little monkey as it is and want ideally a 4 year gap between any children I have and be in my own home married to my man before any more children come along. The urge is so strong tho to have another baby will it go ease off or am I going to be craving babies forever lol! Help!
