Pregnancy Advice?

In the beginning of our marriage, I worked at Target, in the infants department mainly. I used to buy a lot of clearanced items while working. My logic was that by the time we had kids, they would have some nice clothes, even if we didn't have much money.
I didn't hide this from any of my coworkers. All of them knew I was trying to get pregnant. One year, about 8 employees got pregnant at the same time. Of course, I wasn't one of them. After a few years, and no baby, the advice started to pour in.
Everyone considered themselves an expert on baby making. I would walk through the store, and other employees would stop me, and offer advice. Even the single people.
The advice that always made me laugh was "just don't think about it." I can't tell you how many times I heard this advice, and thought to myself, "are you kidding me!?"
I didn't understand it then, and I still don't get it now. How do you not think about the thing you want most in life? How do you have sex, and not think "this could be it." There isn't a day that goes by that I don't think about being pregnant, or hope that I am. Every wish, every prayer, every fast is dedicated to me having children. I can't push it out of mind.

Round 2

Well, the first IUI didn't take. Turns out my progesterone levels on day 7 were really low too, which could mean I didn't ovulate? I don't know, I don't understand the whole thing. The Dr. upped my clomid dosage to 100mg. I went in last Friday, to make sure that I wasn't making too many eggs, but it seems it was too early to tell, and yesterday I got a surge around 2:30pm.
We went in this morning for the IUI, and I had already ovulated, so once again she couldn't tell how many eggs I had released. She is thinking it was 1. I wish it was more. I really wanted a big chance of it working this month.
This time felt different too. I knew I was going to ovulate yesterday, and I had a lot of cramps. I guess that is a sign of ovulation, but I have never felt them before, so I thought for sure that it meant more eggs.
I was so hesitant to tell people about the procedure this time too. I know they all care, and they all want this for us, but it is hard having them all know. Last time during the 2 week wait, I had a lot of symptoms that could mean pregnancy, but always come with my period. Everyone kept telling me that they were good symptoms, and that it sounded like I was pregnant, and in the end, they were wrong. I was so afraid that was going to happen again. My hopes increased so much with everyone's excitement.
So, we'll see what happens next.
