Aww mama, congrats on being so close! Pero please contact your OB or go to the hospital/birthing center right away to get checked, kahit parang "practice contractions" lang, mas safe na confirmed ng doctor kung what's happening, lalo na at 38 weeks ka na. A few of us mums got checked at this point and iba-iba ang situation, iba yung true labor signs, kaya kailangan ng professional eye talaga. Don't wait, better safe, di ba? Keep us posted!
