If you’re a private patient, it might be easier to ask for hl from your gynae. I asked mine during the 34 weeks check up because I’m working 12hr shifts for both morning and night. She understood my workload and granted me 1 week hl to rest first. At my 37 weeks check up, I’ll be getting another hl.
HL depends on your gynae and also your condition. Some gynaes won’t approve unless they feel that you need it.
I just asked directly and shared my reasons for needing it.
