What kind of contacts? I am assuming soft with the mention of a two week trial pair.
I wear rigid gas permeables which have a number of differences with regard to size (smaller) and feel (generally regarded as more uncomfortable than soft).
It took me a few weeks to adjust to the things and each morning I would spend perhaps 5-10 minutes trying to get my contacts in, sometimes more. Nowadays it requires next to no time, but it was an interesting adjustment...
I used to be scared at the situations where they might fall out, but overall...they hold pretty well in place. Most of the times there has been an incident, it happened within the first few months.
