Hi. I'm not sure, but the burning during intercourse sounds a bit like I have had before as a result of a yeast infection.
Penetration was extremely painful and after a few days of that it was painful the whole time... I didn't know at the time that I had an infection.
I have had many infections and I don't always have the same symptoms..
mostly I have the discharge, but a few times I just get a 'feeling' internally and then later I get the discharge.
I have only been to a doctor to diagnose the infection twice.. the first time I didn't know what it was.. the second time I wasn't sure.. and now I pretty much know when I have got one so I just get something from the chemist to treat them.
The first time there was the discharge so the doctor didn't think it was necessary to take a swab as it was obviously a yeast infection.
The second time a swab was taken and I got the results the next day, I think. It wasn't long.. The results said it was a definite yeast infections.. or overgrowth of candida organism... so they knew what to do to treat it.
I have only ever experienced a yeast infection.. so I'm not sure if BV has similar symptoms or not.
I know how frustrating it is.. not knowing.. and interfering with your personal life...
Maybe results of a yeast infection would return sooner to your doctor than BV, so they could call and let you know sooner if that is what it is so you can start the treatment sooner.
I am up to the 6th (final) day of treatment for a yeast infection at the moment and I am not sure that the treatment has actually worked yet... either that or I have some other infection... it feels a little like a UTI. I really hope not.
I hope you get better soon.
