I'm 20 years old and I have been tested by my doctor for everything, no STDs, no bacterial or yeast infections, but i can not have sex with my boyfriend without having a very painful burning sensation. It is not on and off, every single time we try to have sex I can not even bear it. My doctor seems as if she doesn't know what the cause is either, I recently noticed that around the time I started taking this pill is when the burning started to occur.I have also noticed I have been so angry all the time for no reason ever since I started taking this pill. Is this the cause of my problem? I am miserable and I feel like this is the only thing left that it could possibly be. I haven't changed my soap or detergent either. Can someone help?
