Hey mama! Oo, totally normal yan! Actually, someone in my mum group mentioned na ang kidneys natin during pregnancy they're working overtime kasi ng increased blood flow, so mababa ang creatinine levels, it's actually a sign na everything's flowing well. The doctors expect it to be lower than usual when you're pregnant, kaya walang need mag-panic! Since you're seeing your OB in a month anyway, just mention it during your visit para mapace if there's anything else they want to monitor, but most likely okay lang yan. Marami sa atin yung ganyan at walang complications, so take it easy ha!
