Uy, mama, two months delayed is really significant, please see your doctor or go to a clinic as soon as you can, okay? They can give you proper tests and tell you exactly what's happening.
I know the waiting feels scary, lalo na kung first baby, but a doctor needs to check you in person para sure. A few of us mums have been through the worry, and honestly, once you get checked, you'll feel better kahit ano ang result. Don't wait pa, go this week if you can. You've got this!
