Bleeding after taking progesterone suppo

I did my IUI and my doctor suggested to take progesterone 400mg suppositories to insert in vagina morning and night starting from the night I did IUI . 3days after using these suppositories I started getting brown spotting everytime I insert it. On the 6th day after IUI early in the morning I started bleeding like periods with bright red flow(with few clots), i was bleeding for almost half a day. I was terrified and stopped using it. My doctor checked my ET via TVS and it was 10mm, now asked me to stop using suppositories and had put me on duphastone 10mg twice a day. After which I am not bleeding.I had a good ovulation & follicle(18 &19mm)before the trigger shot for IUI. I worried what if becoz of this bleeding I had might result in failure of IUI . Currently I am on the 24th day of my mensural cycle. Can implantation still be possible inspite of bleeding that I had ! Or have I lost it??  I must just wait for the periods to arrive! Pls 🙏 guide me this has driven me crazy .
