Honestly, irregular periods like yours are super common especially after breastfeeding, and Daphne Pills ay birth control so dapat consistent ang cycle mo once nag-settle in your body, pero kung ganyan kalayo ang irregularity mo (twice a month, then delayed 19 days), I'd really suggest checking with your OB first bago mag-adjust ng pills, kasi baka may iba pang reason or kailangan lang ng different brand para sa'yo. A few of us mums tried different pills din kasi ganyan ang experience, at ang dami ng factors, stress, diet, ang body mo after pregnancy, so best talaga na i-confirm with your doctor kung okay pa ring Daphne para sa pattern mo, or if kailangan ng switch!
