wait or test?

Ya
I had my 2nd <a href="https://glowing.com/glow-fertility-program">iui</a> on 4/29. I'm supposed to test on 5/13.. but I don't know if I should just test tomorrow? I dunno by want to be disappointed if it's a bfn .. do you think it's to early to test? I have no symptoms other than afee cramps here & there but I'm in progesterone so might be side effect..
