Anyone know if I can use a canesten pessary 3 weeks after giving birth? I'm breastfeeding so can't take the tablet, I'm also still bleeding but it's a very small amount now. using the cream on its own is not touching it, I'm getting desperate! I've bought a pessary today but there was too many people in the pharmacy and I was trying to hide that I was buying thrush treatment let alone ask questions about it in a queue full of people!
