Test day-14dpiui. Tell me your experience!!

So I had my first IUI done on CD 17 April 8. I did a round of clomid 150mg CD3-7 with trigger shot on CD 15. I never had spotting during my tww. Just sore nipples, had continuous diarrhea with no explanation from 6dpiui to 10dpiui, light intermittent cramping starting a few days ago (felt like light cramps you get before AF arrives), and yesterday I went to the bathroom and when I wiped I had yellowish snotty looking discharge which I've never had in my life. Today is 14dpiui and I tested around 10 o'clockish with a first response 6 days sooner with the wide tip. I did wake up around 3am and go pee so idk if you consider my test pee as fmu. I saw what I think most people would consider a negative, but I'm not sure if my eyes were playing tricks as I feel like I saw a vvvvvvvfl. I tried to take pic but I don't want to post bc I know no one will see what I see.

I guess what I want to know is has anyone else tested 14dpiui or whatever you had done and got a negative? And still ended up getting a positive a few days later? I'm just trying to stay positive but it's hard bc I've been TTC for 6 years and thought this would be it. :( also I have pcos if that helps.
