Does anyone else have thrush! 😩

Kay
Ok so I'm 29 weeks preg and went drs today as I was itching like mad over the weekend at night down below. Tmi (basically my clitoris is swollen/itchy/irritated) you name it! Its horrible. I can't sleep at nights it's so bad. 
My doctor gave me a pessary and cream.. the cream I swear made my itchiness a lot of worse. When will this stop ? I can barely sleep at night anyway let alone now having to itch myself to sleep lol! 
How long does it take for the pessary to work?? ☹️
