mummy2Kaitlyn - first of all congrads on your happy news, how far along are you?
I got thrush with DS and used canasten cream no worries, doc told me it was safe. I havn't used tablets tho, unless you mean the pessary, in which case, it is safe also. However if I was going to recommend one, I would have to say use the cream, it makes less mess, IYKWIM , the cream is easier to clean. The pessary goes all gritty and yik.
