Please go by what ur IUI clinic told u, they usually give a date. The trigger shot can stay in ur system and mess up home test results early on. Better to do the beta hCG they scheduled.
I know that wait feels endless, I've been there. Usually clinics ask u to wait around 14 days for a blood test (beta hCG), thats the most reliable one. Testing too early with home kit can give false negative and just break ur heart for no reason. Hold on a little, ur doing great.
The standard is the two week wait, around day 14 post IUI for the blood test. If u must do a home one, even then wait at least 12-14 days so the trigger injection clears out. Wishing u good news yaar.
Following this, my sister had IUI last month and she was so tempted to test at day 7. Her doctor said wait 2 weeks na. Is the blood test really more accurate than the strip?
