Hey mama, normal yan sa pregnancy kasi lumalaki na ang baby at shifting ang body mo, pero kung sobrang sakit na at hirap ka talaga mag-move, mas maganda pang check mo sa OB mo para ma-rule out kung may iba pang dahilan, a few of us mommy friends kasi nag-complain ng same thing at turned out they needed some stretches or adjustments lang, kaya better safe than sorry! In the meantime, try sleeping with a pillow between your knees, it helped me so much during my first trimester. Sending you a gentle pregnancy!
