Under DHHS regulations, 90-100F is the acceptable temperature range. If the collector had an issue with the temperature, then s/he wouldve ordered you to immediately submit a second sample and under direct observation. The collector would process and send off both samples and indicate in the "Remarks" space that a direct observation collection had occurred, and the reason(s) why.

If you have not experienced any of the above, then you have nothing to worry about.
