nervous, excited.....hoping

Hi. I've been reading the board for a couple of months now. Thanks everyone for allowing me to know that my husband and I are not the only ones out here trying so hard. We've been trying over 1 year now. I had my first IUI last week and am waiting (and waiting and waiting) the results. I took Clomid - even though I ovulate - and had 3 big follicles. Great sample from my husband and we couldn't have felt any better walking out. The past 3 days or so I've felt quite crampy, bloaty, and nausiated. I think it's in my head, but I want to believe. Has anyone else had this about 4-6 days after the IUI? It must be too soon, yes?
