Anxiety rising

Only two days after the first ultrasound, and my anxiety is getting a little worse again. Is baby still ok in there? Thriving? Have I done anything to harm it so far? Will my body fail me again, or will I finally be third time lucky?
I'm feeling a little iffy in the lower abdomen today. I'm not sure if it's a little crampy, or just my gut acting up a little with some bloating/gassiness. Otherwise, no new symptoms here. I tried to distract myself by checking if they had any cheapo maternity clothes on sale at Old Navy. Nope. And what I'd love to get (since I already bought sweaters and shirts and capris with the last 2 failed pregnancies) is pants, but none of theirs are long enough for me. I need at least a 34" inseam. There were some really cute little baby hats though, for $3 or so a piece, so I had to get a couple (OK, a few). I did manage to restrain myself from buying more expensive stuff at the baby Gap - such cute things! Since there doesn't seem to be a lot of unisex stuff out there, I'm almost getting tempted to change my mind on the not-finding-out-baby's-sex thing. At least then I could keep my eye out for things for next winter when the post-Christmas sales come along. I hate paying full price for stuff!
I start my new job on Tuesday. I hope it won't be too nerve-wracking. I'd like to start out with some nice easy rooms before I get put in with harder cases. We'll see what the luck of the draw gives me, I guess. I'm not looking forward to getting up early early again either, but I may just have to make a habit of heading to bed at 9pm.
I hope I'll be able to lay my hands on an U/S machine at some point, so that I can get a bit of reassurance that all's well inside. Since the anesthesia departments don't own one yet, I think that might be a tall order.
