When to test for pregnancy when postpartum....

The title basically says it all.. I know you’re fertile AF after birth. I’ve been cleared by the dr before anyone decides to be a glow hero. I am planning another baby. Also, don’t be all hero on me and tell me I’m dumb, I shouldn’t risk it, blah blah blah. It’s my body, I’ve been given the all clear, I’ll have another baby :) . My question is, when do you do a pregnancy test, if you haven’t had your period yet? Yes ladies can get pregnant postpartum before they get their first period. Would it be the same and wait two weeks to test? Help
