Aww mama, foot pain is super common sa pregnancy especially ngayon na malaki na ang belly mo, pero yung isang paa lang ang masakit ay medyo unusual kaya better check with your OB just to be safe, could be swelling, ligament strain, or something else na kailangan bantayan nang maaga pa lang. A few of us moms experienced random joint pain dito dyan sa pregnancy, pero usually both feet, so huwag mag-alala pero get it checked na para peace of mind mo at para ma-rule out ang anything serious.
