I'm having discharge I noticed it a few days ago it seemed to go away and after having sex last night I noticed it was back and I'm pretty itchy .. it's a yellow color not white cottage cheese looking lol.. I did just get off two different antibiotics could that cause it ? My doctor can't get me in till next week same with my gyno .. I normally get reoccurring bacterial vaginosis so I guess it could be that but not sure what to do
