Uy, mama! Three days delayed is worth checking talaga, pero honestly lang, best way to know for sure is to take a pregnancy test or see your doctor para ma-confirm. A few of my mum friends got anxious waiting, kaya nag-test na agad and it gave them peace of mind. Don't stress too much muna, pero go get checked so you know exactly what's happening with your body, okay? Sending you hugs!
