Pregnancy on target ?

Has anyone done these test thing's , have they ever been right ? I'm a single lesbian will be twenty shortly in a few month's, I've always had artificial insemination <a href="https://glowing.com/glow-fertility-program">IUI</a> in my mind since 18, even if I'm still single by then, I've seen alot of singles do this. It is correct because i won't be doing it til at least 2016-2017 .
