Today is 12th day after my iui. I did my iui on 14th and 15th april 22. I could see light bleeding and also my last periods was on april 2nd. I am expecting a good news to happen but afraid of this bleeding. Doctors suggested my to take progesterone's for 20 days and I am on 12th day after iui. I dunno if I have pregnancy system. I had cramp last night and woke up morning to see the bleeding. Can a women have periods while taking progesterone. Please suggest am I pregnant or it is periods. When I can take home pregnancy test.
