Ay, mama, those tusok-tusoks and the loose poop might be signs na malapit na talaga! A few of my mum friends had the same thing weeks before labor, pero may iba ring parang ganyan for days pa lang before actually going into active labor, honestly, bawat body is different. The light cramps na come and go could be Braxton Hicks or the real deal na nagsisimula, so best to check with your OB na para sure kung how far along you actually are and kung ready na baby to come out, especially since you're already at 38 weeks. Keep track ng frequency ng cramps and message your doc or go in if they get stronger or if may other changes, ha! You're so close na, mama, all the best for your labor!
