Hmm, yan ay unusual talaga, normally Daphne should lighten or stop your period altogether, kaya buti na-notice mo agad! A few of my mum friends who used hormonal pills had similar experiences, and mas naging normal after they switched to a different brand or dose, so definitely worth bringing this up sa OB mo para ma-check kung maybe you need adjustment or if may iba pang dahilan. It's not dangerous pero hindi rin expected na mag-period consistently pa rin after a year on it, so better safe than sorry!
