Mama, go na to your OB ngayon na, hindi worth the risk to wait, lalo na kung intense na talaga ang contractions mo! First time moms especially need to get checked immediately para sure na lahat okay with baby and you. A few of us dito sa mama circle, once nag-start ng intense contractions, pina-check agad namin even if hindi pa regular, kasi ang OB namin always says better safe than sorry, lalo na malapit na ang due date mo. Your baby might be ready earlier pa! Don't overthink, just go and let your doctor check you out. Tell me how it goes, okay? Praying for you!
