Is it okay to take Diflucan nad Valtrex together?

I just got off of antibiotics on Sunday (I had to stop taking them because they gave me a yeast infection). Well, I took the Monistat 1 on Sunday evening and used the external cream. However, I have had HSV-2 for almost a year now as well. I was fine before I started taking the antibiotics. 5 days after taking them, I was really itchy and uncomfortable and had all the signs of a yeast infection. The monistat 1 seemed to have made it worse so I called my DR and they prescribed Diflucan. I took one on Tuesday night and it seemed to help a little, but I am still really itchy and sore. It seems like my Vulva is REALLY dry and now there's a fishy smell. I have another pill, which I will probably take tonight. I have had yeast infections before due to antibiotics. I have little cuts and it's really itchy still with a little burning as well. I don't believe it's an outbreak, but is it safe for me to take the Valtrex and Diflucan together?
