Eh normal je, don't worry! Masa pregnant memang ligaments and muscles around your tummy stretch, so bila bersin or cough terasa pulled sensation tu expected je, a few of us pregnant mums went through the same thing haha. The good news is it's not harmful to baby, just uncomfortable lah. But kalau the pain jadi severe or accompanied by bleeding or other symptoms, better check with your doc just to be safe, okay? In the meantime, you can try supporting your belly with a pillow or your hand when you feel a sneeze coming to cushion the sensation a bit
