Uy, mommy, that's something you really need to discuss with your OB right away, don't wait pa! Kahit na parang normal lang, 3cm dilation at ganyan kalpit na ang due date mo, kailangan i-monitor ng doctor mo closely para sure na lahat okay sa iyo at sa baby. A few of us mums in the group nag-experience ng ganyan, at different ang situation ng bawat isa, some went on to deliver shortly, iba naman it was just early signs lang. Ang point is, yan ang reason we have our OBs, talaga. Call yours now or go to your hospital if may concerns ka, ha? Take care, mamsh!
