Oo normal talaga, lalo na sa second trimester kasi lumalaki na ang baby at umiikot ang ligaments mo! A few of us in our moms group experienced sharp pains or dull aches, kaya don't worry too much, pero kung sobrang sakit talaga or may bleeding, better check with your doctor agad para peace of mind. Kalakasin mo lang ang prenatal vitamins at mag-rest ka pag nakakaramdam ka ng pananakit.
