Wa'alaikumsalam! Honestly, bersin time pregnant memang boleh ada pulling sensation sikit kat perut sebab the ligaments stretch, tapi kalau sakit yang persistent atau ada bleeding, better check with your doctor just in case la, okay? A few of my mum friends experienced the same thing and mostly it was normal, but everyone's pregnancy is different so takde salah nak get peace of mind from your OB-GYN. Jangan risau, most likely okay lang, tapi awal-awal pregnancy especially kita memang lebih alert!
