Teagz - I am sure you have already tried this but have you tried that canaston (sp?) stuff? its a tablet and cream combo?? It might also be worth trying our some branerry capsuals Blackmores has these, dunno if it would help out for thrush but could aid in preventing UTI's one of the last things you want when TTC.

I love cranberry juice and can't get enough of it I use to get UTI's a bit when I was younger and got addicted to Cranny juice then- I also take these (cranny tablets) + Silica Compound which is safe during pregnancy (helps with connective tissue) as well as the BM - Pregnancy Supps. There is little between these and the preconception ones so I figured I might as well finish off those an see how we went.
