Need tips on how to work from home at 29 weeks pregnancy.

Hi All, please share some tips on how to work from home (desk job) for 9am to 6pm without exerting myself. Back pain is real in 3rd trimester. Getting up from seat is not that easy as well. Have tried working from desk and bed (with foldable table). Turns out both are not easy. Thanks in advance 🙂🙏🏼
