Hai mama! At 29 weeks, cramps boleh jadi normal, banyak of us experience Braxton Hicks (practice contractions) yang rasa macam period cramps, especially kalau perut tegang je, then hilang. But since this is your first pregnancy, best to check with your doctor just to be safe, especially kalau cramps tu intense, berulang, atau ada spotting. Better to get peace of mind than worry je, kan?
