Hi Emma,
Just read you post and thought my 2c worth may be helpful. my sis was admitted with her DD at 33w, her BP was up and she had protein in her urine = pre-eclamsia. She had such high levels of protein that they eventually induced her and at 33w4d her DD was born via emergency c section.
I'm exactly at 33w4d today and my BP is up and I'm being monitored very closely at the hosp. From my experience so far- as long as they are closely monitoring you and the urine tests keep coming back ok you'll be fine... You're almost there, only a couple of weeks to go!!
