Help..

So I got treated for chylamdia a couple weeks ago.. & after I got treated I had my period.. I have a problem with my clit part.. it’s itchy sometimes.. especially on the hood part. I went to the doctor for a check up and I mentioned it to her but she said that my discharge looked normal and that she’ll see what it could be.. but in the mean time she told me to buy monistat itchy cream.. I noticed I had a little blood on my clit part.. I did scratch my thing ( I know I’m not suppose to bc it’s sensitive) but I couldn’t help it.. is that why there’s blood?
