Normal lang yan, mamsh! Sa 19 weeks, yung Braxton-Hicks contractions (practice contractions) ay common na, lalo na kung active ka o nag-stress ka. A few of my preggy friends namin experienced the same around that time, isa sa kanila mas maraming tumigas pag gabi o pag tired siya. Pero best talaga i-mention mo sa OB mo sa next check-up para ma-assure ka na lahat okay, especially kung painful siya or may spotting, kasi mas peace of mind talaga kapag nag-confirm ang doctor!
