Mama, that's something you really need to discuss with your OB as soon as possible, ha, hindi ako makaka-say kung normal yan o hindi, pero mas safe na siguruhin ng doctor mo directly kasi importante ang monitoring ng baby growth especially this late sa pregnancy. A few of us mums had similar situations before, and ang doctors namin nag-adjust lang ng follow-up schedule para ma-monitor ng mabuti. Don't worry too much, pero get it checked talaga, okay? Your OB will know best what to do.
