Negative tests but no period

This was my first time doing an IUI. I did the stimulating hormones all before it and did the trigger shot then went in as scheduled for IUI. I’m now 17 days past IUI, 16 days past my temp rise. I don’t have positive tests but haven’t had a period or temp drop yet. Doctor said to keep testing over the weekend and then they’ll do bloodwork Monday if I haven’t started but I feel like this just gives false hope.

Has anyone tested positive this far past an IUI before?? Does anyone have delayed periods after IUI?
