WHEN SHOULD I START!!??

I'm going to plan on renovating my basement for a suite nursery !

-new dry wall

-egress window

-drop down ceiling

-a shower

-snap in floor

-doors

-lighting

-painting

I'm almost 13w, I just need to get the electrical panel up to code and the window done before renovating! AND moving a bunch of crap out of the basement.

When should I start? I dont want to start too late OR too early .

I was thinking maybe when I'm 22w or something. I just dont want anything to happen to baby...and have the work done...for nothing 😖 nervous ! Ugh thanks in advance 😊
