30 weeks... Have to cut back at work- update

Sooo I had my 30 week appointment today and told my doc I was having some Braxton Hicks contractions. She is not happy that they are happening so early and told me I have to cut back at work. Which would be great because I'm really over the whole working thing at this point.

But... I'm a nurse and I work 12 hour shifts. I'm just so worried that when I talk to my boss tomorrow about cutting down to 8 hours or Cutting back on my physical activity that she isn't going to want to work with me.

I can't afford to not work up until I deliver and I want the full 12 weeks to spend with my baby boy when he is here. Ughhhhh!

Update: so my boss has decided that she won't be working with me for my 8 hour days and I will be placed elsewhere in the hospital for the duration of my pregnancy. I'm so frustrated and upset... I really thought she would be understanding and make something work. But I guess not.
