Sayang, lendir yang keluar banyak-banyak on and off memang boleh normal dalam trimester ketiga, tapi dengan sakit pinggang, kepala, and frequent urination, you really should see your doctor or go to the clinic today , better safe than sorry at 35 weeks, okay? Few of my mum friends went through similar things and turned out okay, but a couple had things that needed checking. Don't wait, call your clinic or go to the hospital sekarang, especially dengan sakit kepala and back pain campur-campur. Mula-mula boleh nampak tidak serious, tapi masa pregnant ni kita kena proactive je. Jangan risau, probably fine je, tapi kena confirm dengan doctor. Take care!
