How do I know when I’m ready for #2?

My little one, is 7 months old he will be 1 in May. He’s such an easy baby, sleeps good, never cries unless he’s tired keeps himself occupied. On one hand I want another one because i feel I could handle it and on the other I kinda just want to enjoy how easy he is and have one on one time. My fiancé and I both know we want another and we want them close but just not sure when the right time is. We’ve discussed it several times and next Friday I have a gyno app (pap smear) and I’ve thought about asking him to remove my IUD. My fiancé said he doesn’t care its my body. Anyone else in the same boat? Or does anyone have any advice? I’m just so torn!
