Positive pregnancy test

Abbey • I have 3 amazing kids. A 4 year old boy, and boy/girl twins. Life is 👌🏻.
I just had an <a href="https://glowing.com/glow-fertility-program">IUI</a> done last Wednesday, the 11th, and since this Tuesday, the 17th, I've gotten 3 positive pregnancy tests. Everything I've read says that it's way too soon for that to happen, and because of the <a href="https://glowing.com/glow-fertility-program">IUI</a>, I know I didn't ovulate sooner than I thought. Is it safe to say I'm pregnant even though it's so early? Can you get that many false positives? Anyone else ever test this early?
