Seek medical or treat at home?

I’ve been having a lot of discharge lately, accompanied by some cramping. My last period was Nov 17th for 6 days.

My discharge also kind of burns and has a slight sweet smell, or it sometimes milky white or is tinged a little yellow. I’ve only had one partner.

I feel like it’s BV (I’ve had it before) but idk if I should get swabbed & get an antibiotic prescribed?

If you’ve had BV what was the quickest way it resolved?
