5dpo with IUI

​

​I am having some cramping and I had this thick creamy discharge when I went to the restroom a little while ago. It was a weird yellowish color. I go in for my blood test on Friday. I don't want to get my hopes up!!! I had six viable eggs when I did the IUI. DH and I BD the day after the IUI. I am 36 years old so I am praying it will happen soon. What do you think about the symptoms?
