Labour? 33 weeks pregnant


So I have been having Braxton Hicks the last couple of weeks. But Saturday they came on really strong for a couple of hours and then went away. I woke up yesterday morning feeling awful with terrible Braxton Hicks pain so bad I rang my doctor and was sent in to the Labour ward and was kept for the night to be monitored, there were contractions showing on the machine but I’m not dilated at all so I was given an injection for the baby’s lungs just incase I went into preterm Labour. I was aloud home today on bed rest for two weeks but in the last 4 hours I have been having really intense throbbing/pulsating back pain it’s taking my breath away! Could this be it? Should I wait and see what happens or ring them again?
