Uy, normal yan mommy especially sa first trimester kasi tumaas na ang blood volume mo and your heart's working extra hard for baby, pero since palagi mo nararamdaman I'd really suggest texting your OB na agad or calling the clinic para peace of mind mo, hindi mo kailangan maghintay till next week if you're worried! A few of my mum friends nag-experience din nito pero it varied kung gaano kadami at kakabit sa anemia or other stuff, so best talaga na i-check directly ng doctor mo para sure. Congrats sa baby btw!
