Maternity pay confusion

Hey guys. For background I’m based in England. So I worked for a agency while doing a training graduate program for a year (June 2023-June 2024) and then was meant to start my PhD which would of gave me a full time position within the NHS but due to pregnancy complications I had to defer for a year. The ward I was meant to work on gave me a different position until I was able to continue with my studies but when my pregnancy complications worsened I was gave a sick note with a review every 3 months. Now I am 4 months pregnant, but even though I am technically employed I haven’t worked anymore than 6 shifts before being placed off work. Does anyone know how my maternity pay would work? My ward manager said I don’t qualify for maternity pay, so I looked into stat but i haven’t worked enough hours for that either so what would I apply for? I have an condition that lowers my white blood cell count and the medication they offer during pregnancy for it I am allergic to so working in a hospital while pregnant is next to impossible without serious risks or I would consider working up the hours as much as I can to qualify. It’s all confusing so any advice would help 😂 Thank you!
