Yea depends on ur gynae. Private gynaes esp those who has their own practice typically has more flexibility in giving HL. And if u hve a certain health condition. I was given 4 wks HL due to worsening asthma. My colleague got 1 wk HL as she did not have any health condition, she just tell her gynae she needs the rest before delivery as it's tiring for her as a teacher. Both are private gynaes.
It depends on ur gynae. Mine will give on per week basis and only aft 38w
