Why Your Period May Be Late After IVF
A late period after IVF often happens because of hormones used during treatment. Medications can delay ovulation and thin the uterine lining, which may postpone a period even if a cycle did not result in pregnancy.
Early Signs and Symptoms to Watch
Some people notice mild cramping, breast tenderness, or light spotting. These symptoms can occur with or without pregnancy. Implantation bleeding is usually light and short, but only a test can confirm whether it is related to pregnancy.
When to Test and What Results Mean
Use a sensitive home pregnancy test about 10 to 14 days after embryo transfer. For more detail on testing timing, see guidance from the American Pregnancy Association at https://americanpregnancy.org. If the test is negative and your period still does not start, contact your clinic to discuss hormone levels and next steps.
