Mommy, please reach out to your OB-GYN agad to check this out, side and back pain deserve a quick professional look, especially early in pregnancy. Pero alam mo, a few of us moms experience ligament stretching and muscle aches around this stage kasi lumalaki na ang uterus, pero mas safe talaga if your doctor rules out anything else. Hindi mo dapat mag-worry alone, kaya contact your clinic soon, okay? Take care, mommy!
