So very different this time around

So I finally caved in and called the Fertility Center this morning. I'm still experiencing a lot of pain and discomfort (to say the least!) really low in my stomach (uterus/bladder area). I didn't have ANY pain at all last time around. I keep telling myself that different is good, but I'm actually a little worried. I haven't been weighing myself every day (completely spaced that they want to make sure I don't gain 3-4 pounds in a day - apparently that's some really serious complication going on), and I hate when that's my first answer: duh, I forgot. I'm so good about following their exact instructions. Anyway, turns out that the pain is ok, especially since it's getting better each day. I notice that after a night of sleep and lying flat my stomach doesn't hurt when I get up. But as soon as I'm sitting upright for a little while and then try to stand up, I can't stand up straight because of the pulling and pressure way down low. Ugh. It's almost like I did way too many sit-ups, only it's worse than that. Such a hard thing to describe. Can you tell I'm a little nervous? I'm rambling, even on my blog! I'm going to sign off. Hahaha! Here's to everything being OK! Better than OK! Think babies!!!!!!!
