Anak, I know how much you want this, pero please see your OB as soon as you can, 10 days delayed is really worth checking out properly, kasi maraming reasons pa why delays happen, at hindi lang serum ang makakasagot dito. A few of us moms have been through delays din, and honestly the best peace of mind is getting a proper check-up, bloodwork, ultrasound, lahat, kasi alam natin na more accurate ito than guessing, diba? Your doctor can also guide you on what to do next based on what they find. Sending you hugs, and fingers crossed for you!
