Sayang, please go see your doctor or go to the hospital today, okay? Abdominal pain yang macam tu, especially kalau still hard dan tak improve, kena check. At 21 weeks, better safe than sorry! Iya, working mummies memang aktif, tapi your body needs to tell you something right now, jangan tunggu. Call your clinic or go to A&E, let them scan and confirm everything okay. Pregnancy pain boleh be so many things, tapi doctor kena confirm, bukan internet. Jangan risau, mungkin just ligament stretching or activity, but they need to rule out anything else. Go now, sayang, better peace of mind!
