You may resume regular activities after IUI. In most cases, women can resume intercourse anytime after an IUI procedure. However, doctors may recommend waiting 48 hours before intercourse if a tenaculum forceps is used. As it may cause vaginal bleeding during the procedure.

After IUI, abstain from smoking, alcohol, drugs, and certain medications that could harm embryonic development. Prenatal vitamins, such as folic acid and other supplements prescribed by your doctor, should be taken.

Do a home pregnancy test (urine pregnancy test) 14 days after the procedure, as early tests may give false results due to the hormones used for the fertility treatment. Then, contact your doctor to plan further visits (1).

What Are The Causes Of Cramping After IUI?

Some women experience cramping during the IUI procedure due to catheter insertion through the cervix, which may resolve once the catheter is removed. Cramping after IUI can also be caused by the following factors (1):

  • Uterine irritation because of catheter insertion may cause mild cramping and uneasiness after IUI. However, a few women may experience severe cramping.
  • The procedure is done in the ovulation period, and ovulation can also cause cramps. Medications are administered to increase the number of ova (eggs), which may cause more pain than usual.
  • The fertilized egg’s implantation can cause cramping. It may occur after ovulation, and it can also cause mild spotting and breast tenderness in some women.

Some women may also experience menstrual cramps a few days after the IUI procedure if it is not successful. However, not all cases of uterine cramps after IUI are due to the procedure. Hence, look for other symptoms and the onset of cramps to determine the reason.
