Sayang, varicose veins down there during pregnancy memang boleh happen sebab of the extra blood flow and pressure, a few of us had the same worry! But since your doctor wasn't 100% sure and you're feeling concerned, I think it's worth getting a second opinion from your gynae, just to make sure it's nothing else and get your peace of mind, especially at 32 weeks when things can change. Most cases resolve after delivery, tapi better safe than sorry lah, especially when you're worried.
