Totoo yan, normal talaga especially sa first trimester at around mid-pregnancy, a few of us mums experienced the same thing kaya hindi ka nag-iisa! Yung ligaments mo nag-aadjust pa lang sa growing baby, at the stretching sensation na parang cramps is very common. That said, if the pain is really intense, hindi nagpapahinga, or may bleeding, better check with your OB agad lang para ma-rule out anything serious, better safe than sorry lagi sa pregnancy! Congrats sa first time mom journey mo!
