Things get a little more complicated if your IUI includes certain medications, but the 14-day guideline still applies — and may be even more important.
The trigger shot
If your doctor wants to time your IUI even more precisely, they may prescribe a “trigger shot.” This injection of hormones tells your body to release its mature egg(s) in preparation for an IUI (rather than wait for it to happen naturally). Your doctor will usually schedule the IUI for 24 to 36 hours after the shot.

Here’s the kicker: The trigger shot usually contains hCG to the tune of 5,000 or 10,000 IUs. It’s literally what “triggers” your body to release any mature eggs. (What a multitasker!)
To see why that’s a problem, imagine taking a home pregnancy test a few hours after your trigger but before your IUI. Guess what? It would be positive. But you’re not pregnant — you haven’t even ovulated!
Depending on the dose, it can take about 14 days for the trigger shot to leave your system. So if you take a pregnancy test sooner than 14 days after your IUI and get a positive, it may be a false positive from the leftover hCG in your body — not from new hCG produced after implantation. And false positives can be devastating.
Progesterone supplements

Your doctor may also have you start progesterone supplements right after your IUI. These are designed to thicken your uterine lining to make it more receptive to implantation. Progesterone can also help support pregnancy if your natural levels are low.
Unlike the trigger shot, progesterone won’t mess with a home pregnancy test. But progesterone can give you common pregnancy symptoms whether the IUI worked or not. (It’s probably increased levels of progesterone in pregnant women that causes telltale signs like morning sickness and sore boobs. So supplementing can do the same.)
Bottom line: Don’t rely too much on symptoms if progesterone is part of your IUI plan. Take a home pregnancy test 14 days after the IUI — or when your clinic advises you — and if it’s negative, you unfortunately may have to attribute your symptoms to the progesterone supplements you’re on.
