Hi good evening

Ay bes, that's actually super common, marami sa amin na moms ang ganyan, stretch marks talaga ang prone sa butt and thigh area kasi ang skin doon mas stretched during pregnancy! The darkening you're seeing is normal din, kasi mas sensitive ang skin there, but honestly they usually lighten over time, lalo na after you finish breastfeeding when hormones settle down. A few of us tried Mama's Choice Stretchmark Cream & Stretchmark Serum (pregnancy and breastfeeding-safe, which is perfect for you) and it really helped fade both the marks and the darkness, kahit sa sensitive areas! Keep moisturizing regularly at enjoy na lang na at least your belly is clear, blessing talaga yan!
