Hi, I recently had foreplay over the weekend, no sex was involved. The next evening the inside of my vagina it really itchy and very irritating. I noticed when i went to the toilet there was brownish blood on tissue. I am due on my period so not sure if it is that? Last two days have still been irritating and itchy, not very sore but the blood on tissue is now more of a red colour, so I do think that could be my period? But why is it itchy? I have had thrush years ago before so not sure if this is it, as thrush was a lot more painful than this. thanks
