Advice?

Hey ladies, I’m 31 weeks and 4 days pregnant, I’ve been told I may have signs of pre eclampsia, but the last few days I’ve had non stop horrific pain the the top of both my thighs, to a point when I can’t walk for long, unbearable back pain and some pretty bad lower abdominal pains along with some tightening lasting about 10 seconds. Serve headaches that paracetamol won’t sort and also heartburn that I can’t control. have no clue what I can do to help ease any of this, do you ladies have any tips?

Never had this with my other two pregnancies so it’s all new to me.
