Hey mama, nararamdaman mo talaga kung may bago sa body mo kaya i-get ko ang concern mo, pero honestly one week after period is too early pa for pregnancy symptoms to show up, usually kailangan ng 1-2 weeks more para mag-register sa pregnancy tests at maging obvious ang signs. Best bet is mag-take ng test next week or checkup with your OB para ma-confirm agad, dahil pwede rin yan maging hormonal imbalance, stress, or bug na pumasa sa iyo!
