12DPIUI

Today is 12DPIUI for me, and it was my first IUI. I am taking a progesterone supplement since 2dpiui, and it has made me quite crampy. The cramps have gotten more intense as it gets closer to the end of the two week wait. I have also gotten 5 bloody noses in the past 4 days, bloating, fatigue, moody, (which those 2 are kind of normal). I don't have sore boobs, no nausea, no metallic taste. These things make me feel like I am not pregnant, or maybe I am just crazy. I took a pregnancy test last night, at 7 pm and it was a very clear negative, but I know that is not the ideal time to take one. I am just so depressed, i just want this so bad. Has anyone else been in this situation? or have any advice for me?
