Uy, congratulations sa pregnancy, mommy! But honestly, any tightness or hardness on the side of your belly during pregnancy needs a quick check with your OB, better safe than sorry, lalo na kaya at 7 weeks pa lang. Tawagan mo na lang agad your doctor para ma-check, okay? A few of us moms in my circle always say na mas peace of mind kapag na-confirm ng doctor na lahat is fine. Ingat ingat, ha!
