11 days post IUI

Hey everyone! So I am 11 days post IUI. Had my first IUI done on 11/26/15. I can take a pregnancy test this Saturday 12/12. I took one last night, because it's SO HARD TO WAIT! It was negative. I'll test again on Saturday (that's also the day AF is due.) I was wondering, for those of you who did IUI and got BFP, what were some of your symptoms? Any? I've been crampy since day 1 of IUI. I'm constipated and never have been before. I am sensitive and crying at commercials that would have made me roll my eyes previous to IUI haha. This morning I threw up, and felt fine after that. These are all positive signs pointing towards a positive pregnancy test this weekend, right?! I don't know! How did other people feel after their first IUI or their successful one? I'm analyzing my body's every move!
