Okay lang naman ang nakaharap or nakahiga, mama, yung importante talaga is na comfortable ka at walang pressure sa belly mo! A few of us preggy friends namin, iba-iba kami ng preferred position, pero ang common advice from our OBs is mas better ang left side kasi mas better ang blood flow sa baby, lalo na sa third trimester like you, pero hindi naman harmful kung nakahiga lang or nakaharap mo minsan, basta sigurado lang na hindi ka masyadong pressed down. For peace of mind though, best to ask your OB about your specific situation since every pregnancy is different, pero generally walang big issue yan!
