Am I crazy?

We want to try for baby #2

I'm still breastfeeding but not a lot probably 4 times a day my milk supply is so low now my baby drinks most formula...

AF comes 1 month yes 1 no situation

I'm 247 pounds (230 pounds when got pregnant with first baby)

I really want my kids close in age

Pandemic can't ruin my plans but I'm also scared cause I'm a nurse ugh

What can you ladies advice me be hard but not harsh please....
