Hi,
According to the literature the success rate of IUI is around 10 to 20%. According to the your history the possibilities are:
** If the IUI was successful the urine
pregnancy test might have showed positive result by this time.
** If you want to get clarification, please go for
blood test for pregnancy, which can give more accurate results compared with urine test.
** If the
serum beta HCG levels are more than 25 mIU/mL, it confirms the pregnancy.
** If the test gives negative result, the possibility is that as you are taking the
progesterone tablets because of that you were not getting the periods as the progesterone will protect the endometrium from getting shed.
So, please consult your doctor and undergo a blood test for pregnancy, if it gives a negative result, you may need to stop the progesterone, so that you will get the withdrawal bleeding.
Take care. Hope I have answered your question. Let me know if I can assist you further.
