Sayang, this sounds uncomfortable and at 33 weeks you really should check with your doctor or midwife asap, jangan tunggu lagi. Kebas + sakit berdenyut boleh jadi banyak benda, and they need to assess you properly to make sure baby and you are okay. A few of my mum friends had nerve pressure issues during late pregnancy, but some cases need actual medical attention, so don't guess-guess, just go see your OB or clinic today if possible. Better safe than sorry at this stage kan?
