Superstitions?

Hi all, want to check as I heard some superstitions regarding house works during pregnancy. We are preparing for nursery and have to sell away some furniture. Some items need to dismantle/set up/move out. Is it OK for me to be in the hse? asking as I have only heard abt no drilling into wall etc... what about using screwdriver to dismantle or set up stuff ( not done by me) #pregnancy #superstitions #mums
