Anak, I know this is stressful, pero kailangan mo talaga makipag-consult sa doctor or OB-GYN mo ASAP about this, lalo na kung delayed na ang period mo kahit natapos mo na ang pack. Hindi ko mawawalan ng peace of mind kung hindi mo sinisimulan ang check-up na, okay?
Honestly, a few of my mum friends have had similar scares with missed pills, and puro sinabi ng OB nila na importante lang ma-document lahat ng details exactly kung paano nangyari (para ma-assess nila kung ano talaga ang risk), kaya dala mo lahat ng naaalala mo when you go.
For now, don't worry too much, most cases are fine, pero ito talaga ay kailangan ng professional, not just online advice. Message your OB agad, ha?
