Mama, that pattern sounds like it needs a doctor's check ASAP, please go to your hospital or birthing center now, hindi dapat maghintay!
At 38 weeks with contractions getting closer (10 mins apart) and lasting longer, kailangan talaga ng medical team to confirm if these are real labor contractions or not, they'll check you properly. A few of us mums had similar experiences and ang best peace of mind talaga is having the OB check, especially kung ganitong malapit na ang intervals. Wag mag-atubili, mama, better safe na! Keep us posted, thinking of you!
