I recently started using Gynotex tampons for sex when I'm on my period. Initially DP used a condom and all was fine. I have Mirena for contraception, so was OK to use a soft tampon without a condom. Normally, I change back to a normal Tampax after sex but on 2 occasions last week, I slept with the sponge inside me after DH had ejaculated. Now I have a bad case of thrush (might be worse - slight seaweedy (not quite fishy) and runny clear discharge. Canestan is not shifting it. Any advice?
