Ay sis, it's totally possible na mas maaga ka pa talaga, kung regular ka and you spotted on July 1, baka closer ka na sa 8 or 9 weeks kaya ang bump mo agad na ganitanda, lalo na kung first pregnancy mo, some of us mums noticed na ang belly natin lumaki ng biglaan around that time! Better double-check with your OB ulit using an ultrasound para ma-confirm ang exact dating, kasi sometimes the dates can be off by a week or two depending on kung kailan exactly nag-ovulate ka. Either way, every body shows differently so don't stress too much about it, ang importante lang is na healthy ka and baby is doing well, pero yes, get that sonogram done para sa peace of mind mo!
