I work at a local company where I am being paid $2000/month every month and am expected to work at least 50 hours. However, I normally put in 60-70 hours each week. My question is whether or not I should get any overtime compensation. I think that I saw that in order to be exempt from the overtime there is a minimum salary requirement of $455/week. Based off my monthly salary, in months that have 31 days, I am only making $451/week which is less than the minimum requirement. Should I be getting any overtime compensation?

It's not based on calendar days. $2,000/month X 12 = $24,000. $455/week X 52 = $23,660. Your pay meets the federal requirement for "salary basis" for exempt employees.
