Aw sis, normal talaga yan! A lot of us moms experienced pain or soreness down there towards the end, it's because of all the pressure from baby and the stretching na nangyayari, plus your body's preparing for labor na. But since you're so close na to your due date and the pain is bothering you, definitely mention it sa OB mo next checkup or just call agad kundi kaya mo na, better to be sure, lalo na ngayon na malapit na talaga. Hang in there, mama, almost there na!
