Discomfort at 35 wks

Hi mga momshies, I'm at my 35wks at sobrang likot ni baby day and night. Mabigat na rin ang tummy. I'm currently bedrest due to my condition and I can only lie down on my left side pero most of the time I experience left leg cramps. Any suggestion on how to lessen the discomfort and sometimes pain, I'm only awaiting until 37wks and sked nko for CS
