Hay anak, yan ay definitely something you need to check with your doctor right away, sobrang importante yan lalo na first time mom ka pa lang. Light sensitivity na may connection sa head ay hindi dapat i-ignore, kaya please make an appointment or go to the nearest clinic/ER agad okay?
A few of us moms have experienced weird vision stuff during pregnancy or after, pero lagi ang advice ng doctor namin ay "huwag mag-self-diagnose", kailangan talaga ng proper check-up para malaman what's going on. Sending you strength, mama!
