Wa'alaikumassalam! Sakit di sebelah perut tu boleh jadi pelbagai benda, hun, stretching pain adalah normal, tapi sebab ni sensitive, better you check with your doctor or midwife asap just to be sure, especially kalau sakit tu persistent atau getting worse. Don't take chances at 24 weeks, okay? Kawan-kawan saya selalu cakap better safe than sorry when it comes to preggy pains. Hopefully semua okay, tapi let the pro check first, ya?
