Diflucan while pregnant?

Has anyone taken diflucan while pregnant? I'm almost 20 weeks and I have my third yeast infection this pregnancy. I've heard contradicting things on whether or not diflucan is safe while pregnant. With my other 2 infections I just used monistat 7 but I wanted something faster this time. I'm just nervous about taking it because this same doctor a few weeks ago when I was admitted to the hospital almost gave me ibuprofen for pain until I questioned it being safe in which she was like "Oh yeah you're not supposed to have this"
