Possible pero hindi normal talaga, anak, kailangan mo talagang i-check with your OB para sure kung ano ang nangyayari, because bleeding between periods can be due to hormonal imbalance, stress, or sometimes something else that needs proper checking. A few of us moms experienced irregular bleeding din before, at ang iba namin naging okay lang after lifestyle changes or medication from the doctor, pero iba-iba talaga ang reasons kaya best talaga to get it checked out para may peace of mind ka.
