If you've never had a successful mushroom trip despite multiple tries off multiple different batches, you may just have an unusual reaction to the compound - some rare enzyme that destroys it, as greenmeanies suggested, or maybe just a brain that doesn't respond to that particular form of 5HT2a agonist in the usual way.
At any rate, you've had your blood work done and everything so it should be pretty smooth sailing from here. In all likelihood it was nothing, but you can never be sure with hand-picked mushrooms (outside appearance isn't reliable enough to positively ID a mushroom even for an expert, let alone a 'hobbyist'), and the potential consequences of eating a poisonous cap and then not getting help are so severe, it's always better to be safe than sorry.
I used to shroom a lot but they sorta... stopped working for me after a while. I haven't experimented in years but basically, I took a break for a few months over the summer, started up next shroom season and all I got effects-wise, from multiple confirmed legitimate batches of different strains, was kind of like what you described - a not too pleasant general clumsy/intoxicated feeling, loss of coordination, I also vomited when trying higher doses... I don't know if it's some physiological mechanism that causes some of us to metabolize psilocin differently or what, and the effects followed a normal psilocin chronology (faded off within a few hours to the better part of a day depending on dose).
