At 15 weeks, ang baby ay pwedeng nasa kahit saang position pa kasi marami pa siyang space to move around, so hindi guaranteed kung left or right, basta sigurado kaming normal ang development sa stage na yan! Pero yung pain mo sa lower left, better to check with your OB para masigurado na walang ligament stretching lang or something else, kasi some of us moms felt weird pains dyan but it turned out normal na round ligament pain, pero dapat talaga confirmed ng doctor mo para peace of mind. Wag mag-alala muna too much, pero don't ignore it din, kunin mo na appointment mo para ma-check.
