Would this work?

Ive had to return to my office job full time recently and its been awful. Im 35weeks & just being at work My feet and ankles swell like crazy, my back pain is escalating and im REALLY uncomfortable all day. Cant sit too long in one position it even hurts pelvic area. Even if i try to get up and move around. Do you think a doctor would give me a note to give to my job to work from home? Ive been working from home this whole pandemic its been a nightmare being back this far into pregnancy. I cant take paid maternity leave before baby arrives.
