Uy, I understand you're worried! But honestly, kung delayed ka ng ganito and may IUD ka, kailangan mo talaga makakonsulta ng doctor or OB agad, hindi ito dapat maghintay, mama. It could be a lot of things, pero only your doctor can check if the IUD is still in place or kung may ibang nangyari, and they can do a proper check-up for peace of mind. Hindi kita dapat aalipin dito alone, please go see your OB ASAP, okay? That's the best step.
