BV/yeast infection..or normal??

i had 4 days ago and now my is kinda itchy inside..its not really bad but im jus scared its gna get worse....last time i had with this guy (about a month ago) i ended up getting a bacterial infection..this doesnt feel anywhere near as bad as it did when i had that, but im wondering if i might have that?? or could it just be a yeast infection? i have no discharge or odor, jus a little itching...i also got my period the day after we had , so i dont know if that might have somethin to do wit it 2??...i would just go to the gyno but i was just there a few weeks ago and last time she made me feel like a whor e for being there again cuz i happened to jus be there 3 weeks prior for my annual...what do you think this could be?
