Mama, headaches at nausea during pregnancy can happen, pero dahil 2 days na at persistent, kailangan mo talaga magpakonsulta sa OB mo or sa clinic para sure lang, better safe than sorry, especially with the constant vomiting. Hindi dapat mo i-ignore ang ganito, especially when paired together. A few of my mum friends experienced similar symptoms sa early pregnancy din, pero iba-iba ang reasons, kaya talaga kailangan ng doctor check para ma-rule out kung ano exactly ang happening. In the meantime, try to rest, stay hydrated, at kunin mo yung prenatal vitamins mo as scheduled, pero PLEASE see your OB soon, ha? Hugs, mama!
