Uy, mama, please message your OB or go to the clinic to get checked, kahit saglit lang ang symptoms, importante malaman ng doctor ano nangyari especially since you're 6 weeks pregnant. Don't worry though, dami nang moms na nakaranas ng ganyan, at nandito ka na, kaya mo yan. Your baby needs you alert and taking care, so better safe than sorry, ha? You're doing great by even asking!
