wanting another munckin

So, we did our first IUI a week and a half ago. I am due for my period on Tuesday or Wednesday. I took a preggy test this morning and it was negative. I know that it may be too early to trust the test, but I could not help myself. I am home alone this weekend and just wanted - needed - to know. to know something. I thought it would be easier this time around. Not the getting pregnant part, but the waiting... the iui's... the not getting pregnant. But it is not. I think it may be harder because now I know more about how this works. Now that we started trying, I realize how MUCH I really want this. ANd I find myself slipping back to thinking "what if I am not pregnant this time?" I don't know if I can take/handle the roller coaster again. Anyone else dealing with this???? HELP!
