Aw mama, I feel you, pregnancy hormones can really trigger unexpected skin stuff, and honestly every pregnancy is different kaya normal na may bagong surprises this time around! A few of us sa circle namin experienced similar itchy rashes during pregnancy, usually from heat, sweat, or just how our skin changes, pero since calamine isn't helping and it's bothering you, mas safe na i-check mo talaga with your OB para ma-rule out any infection or pregnancy-specific skin condition, they can prescribe something pregnancy-safe na talagang makakatulong, kaya don't hesitate to message or call your clinic about it.
