mmmm, i have had bad hb also. i find that gaviscon really helped me, and my OB recommended it so it must be ok for bubs. i had hb at about 25-27 weeks then it went away, starting again last week. it does still wake me, but i find if i have a swig of gaviscon when i get up and go to the loo at night, that really helps me.

i cant offer any advice about the pelvic pain though, sorry!
