There's not much of anything that can be done to clear the drugs from your system any quicker man. Typically athletes (I'm assuming you are one since you're being tested for steroids?...) use fast acting and fast clearing PEDs for this exact reason.
Now, the sunny side to this situation is you are healthy and did not do any real damage to your HPTA, and will most certainly recover.
Also, as Walkaway already mentioned, since we don't know the clearance time for nolva and clomid, it is probably not the best idea to introduce either at this point.
Life is one giant learning experience, which unfortunately does not have a rewind button...
Best of luck.
