First response ovulation kit

kristen
So I went and bought a first response ovulation kit. That has 1 pregnancy test and 7 ovulation test. This is my first time ever using ovulation test so with there only being 7 test in a box and not wanting to waste all of them in one month when do you ladies start testing I just ended my period Monday. Do you wait a week after you period or start as soon as your period ends.
