I nearly asked this question late last night, so thanks! And so lots of people get this infuriating itch then?! Nearly drove me berserk last night, although there's nothing else to indicate it's thrush.
Pessaries are ok as long as you don't have a low lying placenta, its also ok to use the applicator. My doctor said you would have to really insert it hard and up very far to do any damage.
Cream is fine. Thrush is driving me mad at the moment!! Glad to hear that I can use loads of cream though, I thought it was suppose to be a thin layer and I'm still itching after starting it on Monday evening.
I have also found that it is worse in bed. I have stopped wearing underwear as I found I was waking up and really sweating (all over, but between legs as well) and that was making the itching much worse.
CrapBag the knickerless option crossed my mind last night, I'm getting horrendous night sweats. Might try it tonight (don't tell DH, I don't want to be fending him off, although how he could find me desirable in this state is beyond me!)
I'd avoid the pessaries and stick to the cream. With my first I used the pessaries on the Drs orders and ended up bleeding. Rang the midwife for advice and she scared the living daylights out of me by telling me to prepare for the worst and then left me for 24 hrs stewing on that sentence. All was fine but I still haven't quite forgiven either of them.
