I usually wear glasses and recently started getting into contacts. Started with dailys like them alot but find them expensive. If i was too buy weekly or monthly, once i open then and use them, has there expiry started or can i use them for a day or 2 and put them in solution? And count the amount of days until they reach a month or week with use?

A 2 week lens is good for 2 weeks once opened, a 1 month lens 1 month once opened. Once they are out of the sterile blister pack they are only good for the period of time on the label (health Canada/FDA approval as a medical device).
If you wear them longer nothing may happen, but just like consistently going over the speed limit there is a greater risk of something bad happening.
Dailies vs. Monthly lens cost break-even point is about 2.5 days on average (Once you factor in solution etc). If you use contacts 1-2 x per week it is actually more cost effective to use dailies.
Also, if you lens has sat in the solution for over a week without being used, you should put it back in fresh solution for 4-6 hours before use. Reduces the risk of infection.
