Ay, spotting while breastfeeding on pills is tricky talaga, a few of us din nag-experience ng ganyan, and honestly it's best to check with your OB kasi bawat katawan naman iba ang reaction, lalo na ngayon you're breastfeeding pa! They might need to adjust your dosage or switch you to another pill that works better with breastfeeding, kaya huwag mag-atubili mag-follow-up agad.
