Western Blot while on ABX & Aura...

Went to see my LLMD today for my western blot results. Turns out that although the doctor ordered the test, the office staff never filled it out on my lab paperwork, and so no western blot. They took more blood today and are sending it out now. But I was just thinking, I've been on Doxy for a couple of weeks now for Bart which was positive last time. Will this affect the WB results?
Also, I had the STRANGEST aura in my left eye last night. I've never experienced anything like this. It was a half moon, bright prism-like white/blue/yellow, and got larger over about 30 minutes until it finally disappeared. I've definitely been feeling worse since being on the Doxy, but this freaked me out a little. Has anyone had this? Is it the abx or the bart? Thanks!

I tested positive for Bart, and the NP said that she thinks I also have Lyme. She put me on Doxy saying it would treat both. But I am going to speak to them when I go back for the WB results because I feel worse on the Doxy...
