nexplanon, period AND bv

I got my nexplanon implant a month and three days ago, and 12 days ago, I started my period!! Usually theyre about 5 to a week long but it's STILL going and it doesn't look like it's going to end anytime soon!! I also got a small case of BV and blood and that other nasty smell, is NOT pleasant at all. If you can be kind enough to leave any tips, experiences and remedies for bv/my long period, that would be VERY HELPFUL! Thank you so much :)))
P.S. I haven't had sex 2 weeks before I got the birth control and I got bv the same week I had sex.
