Alah, sakit pinggang dan mengeras kejap-kejap tu memang normal la dekat akhir pregnancy, a few of us went through the same thing! The fact that baby gerak elok je is a good sign, and kalau dah buat senaman semua bagus la sudah. Try resting more, pakai maternity belt kalau ada, dan jangan berdiri lama-lama; one of my friends swear the warm compress on her lower back helped her through the last few weeks. Tapi kalau suddenly the contractions jadi regular atau ada bleeding, rush to your hospital la, better safe, and of course update us bila dah bersalin! All the best, mummy, you're almost there!
