Ay, 8 days is a bit longer than what most of us experience, usually around 5-7 days lang ang normal, pero honestly, it can vary talaga especially kapag mixed feeding pa kasi ang hormones mo pa rin nag-aayos. A few of us mums noticed our periods were all over the place for a few months after we started combo feeding, so hindi ka nag-iisa dito! That said, best check with your OB lang to make sure everything's okay, especially kung iba-iba ang flow or may unusual symptoms ka na. How's your cycle been since you started mixed feeding, first time lang itong ganitaaan?
