Sis, normal lang yung occasional cramping at 38 weeks, maraming moms sa circle ko nag experience nito, parang Braxton Hicks or just the baby settling lower, pero kung painful talaga ang lakad mo, that's worth mentioning to your doc sa next visit, kasi baka need mo mag adjust ng activity muna. Ang IE naman ay ginagawa lang ng docs pag ready na talaga or pag may signs na, so hindi yan automatic pa even at 38 weeks, kaya relax lang, basta if the pain gets worse or may other symptoms, don't hesitate to call your OB na agad!
