Mama, please see your doctor or OB as soon as you can, hindi basta-basta dapat i-ignore ang ganitong feelings, lalo na at malapit mo na lang i-deliver. At 34 weeks, it's better safe than sorry na ma-check ng doctor kung normal lang or may something else na nangyayari, especially with that painful sensation at the sudden urge to urinate. One of my mum friends had similar concerns and her OB reassured her agad, pero kailangan talaga ng check-up. Alam mo naman, better to be sure na lahat ay okay sa baby at sa'yo. Let me know pano ang resulta, ha!
