Uy, mama, I know it's scary, lalo na first time! But honestly, with brown discharge and cramps, kailangan mo talaga makakonsulta ng doctor or go to the hospital ngayon na para ma-check properly, hindi kaya i-guess guess ang ganitong signs, especially this close to your due date. Better safe than sorry talaga!
A few of us moms went through similar things near the end, pero bawat pregnancy is different, kaya lang talaga ang best thing is to let the doctors assess you directly. Sige na, go na!
