I think I'm out

Sheets • Ttc #1 3 years of marriage . Getting desperate ! But keeping the faith
Super depressed today .ihad my first <a href="https://glowing.com/glow-fertility-program">IUI</a> on 21 June  I'm on 9dpiui and my symptoms have vanished . I had sore nipps and tiredness from 2 dpiui until today. I have resisted taking a test until now because I'm scared . My period is expected in 5 days . 
I guess my progesterone has dropped and now I'm just waiting for af.😔
Anyone had sore nips that stopped hurting yet got their bfp
Sorry this may seem a repetitive boring post but I just had to vent 😔😔
