Well...thrush is inside you...so applying it only on the outside aint doing nuthin !!!!
Get yourself some inner health plus...i got it 4 times last pregnancy and it was doing my head in. The canestan would work.....but 2 weeks later i would get the thrush back. I bought some inner health plus (levels out the good/bad bacteria in your gut...) and got some canestan pessaries....and never got it again. Seriously....it will be the best $25 you will have spent....
