Ay, alam ko yan! Kami ng kaibigan ko, lahat nagkaroon ng ganitong itchiness around the same time sa pregnancy, ang dami naming gabi na kami lang nagscratch ng arms at legs haha. Honestly, ask your doctor about it next appointment kasi sometimes it can be pregnancy cholestasis or just the skin stretching (especially sa 37 weeks na, ang laki na ng baby!), pero marami ring nakahanap ng relief sa moisturizing heavily, cold compress, or avoiding hot showers, one of my mum friends swears the itching stopped agad when she switched to gentler soaps. Importante lang na i-check mo, lalo na kung super intense na talaga at may bumps or anything unusual, para sure lang.
