Ah bes, normal lang yan sa pregnancy especially around that stage, ang baby lumalaki na kaya nag-shift ang buong posture mo, at yung ligaments mo nag-relax din dahil sa hormones, kaya super sensitive ng hips at lower back! A few of us moms experienced that sharp pain din, parang feel mo talagang mababalian ka, pero as long as mawawala siya pag gumalaw ka or nag-stretch, usually okay lang yan. Pero since 10/10 ang sakit mo, mas better pa rin i-check mo sa OB mo just to be safe, basta nandoon ka na, pwede ka ring magtanong ng stretches na safe or kung kailangan mo ng support like a maternity belt, maraming moms swear by those! Take care, mommy!
