Sayang, please go see your doctor or go to the clinic today, sakit perut during pregnancy kena check, especially kalau ada batuk sekali Could be round ligament pain (very common at 12 weeks!), or bisa jadi something else yang perlu tahu, so better safe than sorry lah. A few of us mums experienced weird aches during pregnancy, tapi each case lain-lain, so jangan self-diagnose, just get checked out, okay? Take care!
