Anak, I really understand why you're worried, that's such a scary realization! But please, go see your OB-GYN as soon as you can, okay? Hindi ito dapat maghintay. Your doctor needs to know exactly when you took it and how many days, para ma-assess niya properly ang situation with your baby. That's the only person na makakapag-give ng real answers based sa your specific case.
I know it's stressful, pero honestly marami sa amin mums ang nakadiligencia ng iba't ibang gamot nang hindi pa alam na buntis, at lahat naman okay ang babies namin, pero ikaw talaga dapat marinig from your OB directly, kasi siya lang ang makikita ng full picture mo.
Sending prayers your way, mama. Kaya mo yan.
