Uy mama, that sounds like something you really need to check with your OB right away, hindi pwedeng i-guess guess lang yan, lalo na at 33 weeks ka na! Some things are normal sa pregnancy, pero may iba na kailangan talaga ng doctor to look at, so please don't wait, okay? Call your clinic or go to your hospital if kailangan urgent. Better safe than sorry, especially ngayon na malapit na ang due date mo. Let me know how it goes, ha!
