Aw first time mom ka! Mine started showing around month 6-7 ng pregnancy, lalo na sa belly and sides, tas nagpatuloy pa until delivery talaga. A few of us tried different creams and I swear by Mama's Choice Stretchmark Cream & Stretchmark Serum, they're pregnancy-safe and breastfeeding-safe, and I noticed my marks lightened after a few months of consistent use, plus the smell is nice kaya sanay gamitin araw-araw. But honestly mommy, genetics plays a big role din, so kung may history sa family mo, mas likely ka makakuha, pero hindi siya end of the world, most of ours faded over time naman!
