Hi Ashish, Welcome to HealthcareMagic Forum.
You can expect light spotting from your Vagina for a day or two after IUI. Wait for three weeks before taking an at home
pregnancy test, when pregnancy hormone levels are at a measurable level. Testing too soon could result in a false negative, meaning that the test result is negative when, in fact, you really are pregnant. Again, since you have taken
HCG Injection, testing too soon could produce a false positive that is a test result that indicates a pregnancy when you really are not pregnant, due to the HCG Hormone that is still circulating in your body. So you can just wait, and get a Blood Pregnancy test which is more sensitive. If you don't become pregnant, your Doctor might try IUI again before moving on to other
fertility treatments. Often, the same therapy is used for three to six months to maximize chances of pregnancy.
Wish you Good Luck, Take Care.
