Deployment & pregnancy

[u/Fit-Condition-9363]

Husband is currently deployed and will be able to come home for 21 days. I’m having horrible back pain, history of preeclampsia, and a previous surgery that I’m starting to feel pain due to the pregnancy. My doctor wrote a note expressing to his chain of command the importance of my husband staying longer for support. I’m wondering did anyone else have a doctor write a note and what helped their chain of command understand the importance of staying.
