Ay, 27 weeks pa lang kaya maraming changes pa sa katawan mo, mama! Ang pain under the breast area during pregnancy ay common dahil sa weight ng uterus, ligament stretching, o kahit skin irritation from sweat and heat, lalo na since nag-iinit na talaga dyan sa inyo. Since nag-try ka na ng walang underwire at nag-heat pa, definitely check with your OB para ma-rule out kung may iba pang reason like infection or muscle strain, kasi hindi dapat nag-persist ang ganitong sakit. A few of us moms swear by going braless or using cotton sleep bras na walang support lang para comfortable at hindi nakakairita, pero most important talaga ay makita ng doctor mo to be sure lahat okay lang sa baby at sa iyo.
