should I test today or tomorrow ?

Should be getting period on June 17th according to my tracker. Did my first <a href="https://glowing.com/glow-fertility-program">IUI</a> last Saturday so June 3rd some members said wait 9 days technically I counted today is my 9th. I have 2 pregnancy tests a cheapy one and a clear blue. I guess I'm worried to waste them I avoid using it and just waited to get my period and skipped doing the blood test at the clinic. My husband really wants me to go in next Saturday to do the blood test so worried about being disappointed. Our first cycle at clinic was February did natural and getting the call upset me so much saying sorry your results came back negative so ever since I never did a blood test I said ok if I'm late I would just do it unforuntaltu I kept getting my period? Would you ladies try today or tomorrow at earliest I can't stop thinking if I should wait or go for it ? What would you do ??
