Aiyo nail fungus is so stubborn lah, even before pregnancy pun hard to treat! I'd really suggest going back to your doctor or maybe get a second opinion from a dermatologist, fungal infections during pregnancy need extra care sebab some treatments are a no-no, and they can sometimes spread if tidak di-treat properly. A few of my mum friends had similar issues and one of them had to try a few different prescriptions before it finally cleared, so don't lose hope but definitely let a doctor guide you on what's safe for baby. Meanwhile keep the area dry and clean, and try not to scratch even though I know it's maddening! Hope it clears up soon for you, mama.
