Aw, ang dibdib na manikip with cough and sipon ay super common sa pregnancy, lalo na by week 29 when the baby's taking up more space na, a few of us went through the same thing! Pero since may ubo ka na, better check with your OB just to rule out anything else, kasi sometimes it's just the weight of the baby pressing on your lungs but sometimes it can be a respiratory thing na kailangan manage properly during pregnancy. Hopefully it's just the baby bump making things tight, pero peace of mind with your doctor is always worth it, especially this late in pregnancy na.
