I Had An Iui On Last Sunday 7/15 And I

I had an iui on last Sunday 7/15 and I have been feeling very hungry and eating alot ever since. Little bit moody but it is not bad. Other than that, I don't have any other symptoms. I heard that implantation usually occurs 3-12 days after iui and I just have no idea if something is going on in my belly or not. I had progesterone test last friday and it was 8.51ng/mL. I still have to wait longer to do pregnancy test so I am just anxiously waiting..
