Wa'alaikum assalam sayang! Memang normal je periode ni, especially kalau tgh makan, uterus kita tengah besar dan ligaments tengah stretch, so sometimes boleh rasa seperti period cramps tapi takde cramping yang serius. A few of my mum friends yang first-time juga cakap ada je rasa macam tu around 25 weeks. Tapi please mention to your doctor dekat next check-up, especially kalau discomfort tu consistent or get worse, okay? They'll confirm everything is fine with your baby and just set your mind at ease, first pregnancy memang banyak worry, totally understand. You're doing great, mama!
