Sis, positive TVS and serum blood PT usually means yes, may baby ka na talaga! Pero since irregular ka at first time, mas important pa rin na makita ng OB mo in person para ma-check kung saan exactly ang baby and kung healthy lahat, hindi lang results lang ang basis, kailangan physical check din. I know mahirap mag-appointment sa probinsya, pero try mo mag-call sa clinic mo and explain na kailangan mo urgent, maraming ob na nag-accommodate for cases like yours, lalo na first pregnancy. Congratulations po, at sana mabilis mo makuha ang slot!
