Mama, importante talaga na malaman mo na, please talk to your OB or midwife about this, kasi they can give you the best advice based on your health and plans. A few of us mums have asked the same thing, pero ang truth is, kahit breastfeeding, hindi fully guaranteed na protected ka from getting pregnant, kaya it's really best to get proper guidance from your doctor. They can recommend options na safe while breastfeeding, so you're covered at peace of mind. Proud of you for thinking ahead, mama!
