It's best to always know what your base lines are before doing a cycle. Yes the online private labs you have to pay but it's not bad, about 150 for a pretty comprehensive test.

As for the Endocrinologist suggestion above, some are OK, some are just as clueless as GP. I would still first just get a copy of the test from your office. I just walk in and ask the front desk. They will make a copy. It's not a big deal, it's already yours. At least then you will know what he tested.
