I'm certain I've got thrush. Sore and itchy. The chemist won't sell me anything without a prescription but the midwife says pessary and cream are fine to use and the GP will prescribe them. But, I can not get an appointment with the GP and have tried and failed twice to get a telephone appointment due to being a teacher and unable to answer my phone in lessons. My local tesco sells them off the shelf. Would it be majorly wrong to just buy and use it? I'm 33+3.
