Hospitalization Leave

I’m on my 30th week too! the previous check up I went to see my gynae and asked for HL, my gynae said I need to be fair to my employers. Was taken aback with his response. I told him I was super tired and have backache, instead he told me to see a physio therapist. And he can’t help me if I don’t help myself 🙃 I’m also trying to get HL as I’m super exhausted from work, but i don’t know how else to tell my gynae.
