Hello lila and welcome!

I am glad that you have found us as I am sure you will have a lot of questions.
If you have not already you will want to go to the "New to Lyme...start here" because there is a lot of information there that will be of help! Also you should be doing a few detox methods to get rid of the toxins that the abx will cause. www.tiredoflyme.com/detox-methods.html
The rash can appear quickly, but if you have had symptoms that indicate Lyme, it is possible you have had it longer and the LLMD can help you determine that. There are times people have gotten lyme and not even known they had a tick!
I would definitely do the abx longer. That definitely is not long enough. Hopefully others will be along that do abx and will be able to help you to know how much and how long. I don't have experience with antibiotics.
Wishing you the best!
Tested Igenix positive for Lyme March 2016.
Lyme symptoms for possibly 40+ years but severe in the last 5 after traumas to the system.
Currently treating with Buhner's Protocol for Lyme and Bart while waiting for a LLMD visit.
