First you said a click, then a clunk. You have given us absolutely no information about your bike, how long ago it had service, what equipment is on it, which makes assisting you very difficult. That being said, from your 2nd post I would say that either the left (adjustable) or right (fixed) cup is loose, or your bearing is out of adjustment.
1. Put the crank arms vertical, grab both and move them left and right (across the bike, not in the normal pedaling direction).
2. Stand over the bike and put your weight on one pedal, rotate the cranks till the other pedal is down and repeat.
1. If you feel play with your hands then the bearing is out of adjustment
2. If you feel shifting or hear a clunk when using your feet, then one of the cups is loose.
(both may be true)
Riding the bike one day if only the 1st is a problem may not hurt, but no guarantees.
If the 2nd procedure indicates a loose cup absolutely do not ride. You could be stranded or cause damage to the threads or bottom bracket parts.
