I have been treated with BV earlier this year, and my bf and I had contact 3 weeks ago. after a few days, I noticed my vagina got itchy and I had some grayish discharge, and I just observed and wait what it is till I got my period. After my period I now observed a yellow discharge but I don't feel itchy anymore. I went to my OB gyne and she diagnosed it with chlamydia, but I never had undergone any lab tests with her, and she just said it's chlamydia because my bf is an american

. She prescribed Doxin for 10 days and I started taking it. I went to another doctor. The OB told me it's a BV so I had to take neo penotran for 7 days, and then I told her that i'm taking doxin as well. Now on my 7th day of taking neo penotran and 8th day of taking doxin, I noticed that there's blood(not heavy bleeding) on my underwear. I finished taking neo penotran, and still there's blood, and i am now on my last day of taking Doxin, I have noticed the yellow discharge is not gone and there's blood, and I feel some light pain in my lower belly. I am not sure what to do and what is this. please help
