Pprom advice

I have been off work since 8 weeks with hyperemesis. I am now 19 weeks. I had a pprom at 16 weeks following my amnio. Amazingly the sac healed and the fluid is getting back to an ok level. It’s at the lowest end of normal. I’m under the care of a specialist fetal medicine unit and have another scan on Friday. My question is what should I do about work? My hyperemesis is fading slowly and I’m getting some energy. I have a 50 min commute and work in an office. Should I be thinking about going back to work? I’m so worried I put the health of my baby at risk. I feel we’ve already had a miracle that the pprom hasn’t ended in tragedy. Any opinions, advice, appreciated x
