anxious me

Anxious me took the pregnancy test the cheapy one and showed negative 9 days after my <a href="https://glowing.com/glow-fertility-program">IUI</a> it was last Saturday June 3rrd some members said wait after 9 days i contemplated doing it tomorrow. I keep feeling like I'm not pregnant I guess I was hoping for really sore breasts and implantation spotting I know every body is different should I try again on like Wednesday or Thursday ? Period due June 17th next Saturday where the clinic has asked me to come in for blood test. I'm so sick of all this and now feel stupid for testing today. What would you guys do almost don't want to waste my time ? I'm not upset at the negative because part of me has hope of what if it's not accurate because it's to early maybe ? I don't what to think anymore I keep telling myself I'm  not pregnant
