Can you take an early result pregnancy test 2 weeks before your period but you have already skipped your last period?

Absolutely, if you've skipped one period go ahead and take the test if you suspect a pregnancy. You might get a chemical pregnancy result though, where you get positives at first but a failed implantation would give later negative results. Keep in mind Ovarian cysts, Tubal pregnancy will show up positive as well. Good luck testing hope you get the answers you seek.
