DOT MEDICAL CARD

So I have a question in regards to the medical card.
When I first got my permit a few months ago I got a 2 year medical card which will expire in september 2017. I got hired by schneider a month ago and retook the physical at their orientation at another state. Their doctor gave me a 3 month certification and told me to go get a sleep apnea test. I am no longer with schneider and I will have to pay for all of the expense. Now here is my question:
Is my first medical card still valid? Does the doctor that gave me my 3month card report the physical to my state's dot? Does the dot have some sort of system to track our physicals and know if we are self-certifying or not? Is there anyway I could at least take another physical without having to take the sleep apnea study?
any info would be much appreciated!

 

Thanks for the advice. I'm working for an IC right now and don't plan on going back to any of the megas anytime soon.
do you guys know anything about this? I found it on FMCSA'S website
"FMCSA amends the Federal Motor Carrier Safety Regulations (FMCSRs) to require certified medical examiners (MEs) performing physical examinations of commercial motor vehicle (CMV) drivers to use a newly developed Medical Examination Report (MER) Form, MCSA-5875, in place of the current MER Form and to use Form MCSA-5876 for the Medical Examiner's Certificate (MEC); and report results of all CMV drivers' physical examinations performed (including the results of examinations where the driver was found not to be qualified) to FMCSA by midnight (local time) of the next calendar day following the examination. The reporting of results includes all CMV drivers who are required to be medically certified to operate in interstate commerce, not only those who hold or apply for commercial learner's permits (CLP) or commercial driver's licenses (CDL), and results of any examinations performed in accordance with the FMCSRs with any applicable State variances (which will be valid for intrastate operations only). For holders of CLP/CDLs (interstate and intrastate), FMCSA will electronically transmit driver identification, examination results, and restriction information from examinations performed from the National Registry to the State Driver's Licensing Agencies (SDLAs). The Agency will also transmit medical variance information for all CMV drivers electronically to the SDLAs."

 

Now, is there anyway for the doctor who gave me the two year card to know that I have a 3 month medical card pending sleep study??
