positive?

TW: positive pregnancy test

Hi! I had my first IUI this cycle after 2 early miscarriages. I triggered with 250mcg ovidral on 9/8 at 4:30pm and had the IUI 9/9 at 2:30pm. I’m 13 days post trigger and 12dpiui and got a very clear positive on a frer with an afternoon urine. Just wondering if it’s the trigger still or a legit positive 🥹 any advice or experience would be greatly appreciated! 💕
