Wanting to conceive again.

So, never thought I'd feel this way. And it isn't baby fever as I had a scary pregnancy and ppd. But I kinda want to ttc again. My son is 4 months and I just kind of want to get pregnancy and another child done before he's at a much bigger age. I just want to get done with the baby stage at the same time. I don't know if that sounds bad but the PPD was horrible and I just want to get this over with. I've told my husband and he is definitely on board but not for this moment. And idk anyone in the same boat?
