Breakthrough bleeding? Pregnant?

Does this look like breakthrough bleeding? I have skipped my period for 3 times now and I’m in the middle of a pill pack and this is what has been showing up for the past two days. Could it also be a sign of pregnancy? I had unprotected sex 5 days ago. It’s also worth noting that I have BV and just finished taking my last antibiotic pill today. I have also had some cramps while experiencing this bleeding.
