Miss being pregnant

My baby is now 6 days old and she is my third baby and I just can’t shake this feeling of really missing being pregnant. I don’t know if I’m just sad my pregnancy journey has ended or whether I do actually want to be pregnant again I’m not sure. After the birth I was adamant I wanted no more babies but now I just can’t get rid of this feeling like I really want to be pregnant again, my partner has already said he wouldn’t mind more children and jokes around about me not starting birth control. I know I wouldn’t get pregnant straight away as there would be risks and I want to enjoy my new little baby aswell. Had anyone else felt like this after giving birth and so soon? Did the feeling go away or did you try for another baby?
