Bfn after injecting Ovidrel

I took the trigger shot “Ovidrel” at 7:45pm

i was just trying to see if it came into my system so i took a pregnancy test after an hour but came out to be negative..is this normal or is something wrong? I also took a opk just to see if im close to ovulation and negative..here are the results im doing my 2nd

IUI

w/ medication i have one mature follicle on my right measuring 20mm 💫🙏🏻

EDIT***next day test results

So now im getting STRONG lines for ovulation is that because of the ovidrel or im going to be ovulating? I now see a faint second line on my hcg aswell! My iui is scheduled tomorrow 💫🙏🏻 we did BD last night and cant BD today as my doc instructed...
