BV please help!

My boyfriend and I have been smelling this odd fishy odor lately after sex for about a week now. I did some research and found out that I have bv (bacteria vaginosis) I have been eating yogurt, taking apple cider baths, and even did a rePHesh cleansing treatment to get my Ph balance back on track and nothing seems to work. I don’t have insurance so going to the gyno isn’t an option for me. Is there anyone that knows of anything I can take over the counter or any home remedies I can do to get rid of this? Please help it is driving me crazy!
