Sayang, please jangan tunggu lagi, pergi jumpa doctor atau go to clinic harini jugak, okay? 25 weeks with that kind of pain for 3 days, especially kalau dah tak boleh jalan and your back pun sakit, that needs checking properly, bukan just MIL's okay lang je. Better safe than sorry with pregnancy, trust me. Doktor kena assess properly apa yang happening. Don't delay, ya?
