August 12 po dumating means ko 2 days lang po tapos august 16 po nag ka spotting po ako

Aww, I understand kung bakit ka worried! Spotting after your period ends can happen for different reasons, sometimes it's hormonal, sometimes it's from stress or exercise, pero since you're trying to conceive, it's best to check with your OB para ma-rule out anything and ma-understand better ang cycle mo. A few of us mum friends also track our periods religiously using apps or calendar para ma-identify ang pattern, kaya when something different happens, alam natin agad, pero talaga, ang best approach is to get checked so your doctor can guide you ng maayos, lalo na ngayon na seryoso ka sa plans mo ng maging mom. Fingers crossed for you!
