Hi mama! Breakthrough bleeding while on the pill ay normal talaga, especially sa first few months pa lang ng pagsisimula or if you've recently switched pills, ang katawan mo lang nag-aadapt sa hormones. Since konti lang ang bleeding mo compared sa normal period, that's actually a good sign, pero if it continues or gets heavier, mas maganda pang i-check with your OB to make sure everything's okay, kasi sometimes it can be something else or just need ng dosage adjustment. A few of my mum friends had the same experience with Daphne at after a couple of cycles bumaba na, so don't worry too much!
