Hi mama! First thing, please see your OB as soon as you can, especially since 32 weeks ka na and it's getting heavier. Better safe than sorry, lalo na 'pag nag-increase na 'yung discharge, okay?
I know it's worrying, pero honestly the best person to check this is your doctor, they can do proper tests and make sure baby and you are both okay. A few of us moms went through different discharge concerns during pregnancy, at nakita namin ang doctor para may peace of mind. That's really the safest move right now, sis. Sending you love!
