The medicine your doctor started after the IUI can delay your period even if you're not
pregnant, so a negative test on day twenty-nine or thirty isn't the final answer yet.
Next Steps
Repeat a urine test in three to four days, or ask your fertility doctor for a blood test for an earlier, clearer answer.
Health Tips
Please don't stop or change that medicine on your own until your doctor tells you whether to continue or stop it.
