Oo normal yan, momshie! Sa akin din nagstart ang back pain at pelvic pain around that time kasi lumalaki na ang uterus at nag-shift ang center of gravity mo, plus ang hormones are loosening everything up na, parang ready na ang body mo for pregnancy changes talaga. A few of us mums try pang prenatal stretches, warm compress, at proper posture (mahirap pero it helps!), pero since you're still early, better check with your OB para ma-rule out kung may other causes din at ma-guide ka ng maayos para sa next weeks, wala akong gusto na ma-worry ka ng walang kailangan, you know? Congrats sa pregnancy, mama!
