Sayang, back pain and pelvic pressure boleh jadi normal dekat akhir pregnancy, tapi since you're noticing these symptoms at 35 weeks, please see your doctor or go to the hospital straightaway , better safe than sorry, especially kalau ada discharge or contraction juga. A few of us mums went through this and turned out fine, but only the doctor can check properly whether everything is okay with baby. Don't wait, okay?
