Uy, ang exciting ng waiting game na yan! Honestly, it's super common na mag-delay pa ang period after coming off hormonal pills kaya don't stress muna, a few of us tried conceiving right after stopping BC and it took a couple of cycles para mag-regulate completely ulit. Since your last PT was dec1 and it's only dec9, pwedeng too early pa talaga or it could just be your cycle adjusting after the althea; I'd say test again around dec15-16 if walang period pa, or just head to your OB para sa blood test if you want confirmation sooner, mas accurate siya at mapapakita agad if may buntis even before the PT shows. Better safe and sure lang, di ba?
