Ay alam ko yan, mama, pag malapit na talaga, maraming signs na yan like backache at difficulty walking kaya understandable mag-worry ka, lalo na 2nd baby mo at malapit na ang due date mo! But honestly, better to check with your OB agad about the back pain, especially since you just had a checkup yesterday, sige lang mag-message or call your doc para peace of mind mo, kasi pwede ring iba ang cause at alam nila best what's safe for you ngayon na malapit na. Kaya mo yan, at since normal ang una mo at cephalic na ang baby, good signs na yan! Rest muna habang naghihintay ng labor signs, at huwag mag-worry ng sobra, your body will tell you when baby's ready talaga.
