My Labor & Delivery scare

Mr. W returned from his 8 day business trip to Japan on Sunday. He arrived while we were at Mass and since I was hungry again we decided to go eat brunch at Utopia Cafe. As we were crossing Belmont, I took a serious digger. These stupid Kohl's flats have always been slippery, but I forget how bad they are. Anyway my heel slipped forward and I did the splits (which I can't do when I am not pregnant) landing on my rear and my knee. It hurt a lot and I knew I'd have a giant bruise on my knee, but I didn't really think about it beyond that. I was still feeling plenty of fetal movement, in fact he showed no signs of slowing down his acrobatics routines.
I mostly sat on the sofa the rest of the day, but did do a brief little round of trick 0r treating. I read another pregnant woman on the internet had fallen on carpet and landed on her stomach. Responders were all advising her to call her dr to be evaluated. I didn't think this would apply to me.
The next day, Mr. W took the day off of work to recuperate from his trip and we ate lunch at Dick's Kitchen this time, stopping by Zupan's on the way home for groceries. That walk home was really rough on me and I decided that maybe I should call the Dr. just in case something had ruptured. The nurse told me that she thought I was fine, but she wanted to speak with my Dr. just to be certain since he was in the office. When she got back on she informed me that he wanted me to go immediately to L&D to have a NST and be monitored for 4 hours.
Hello! That freaked me out! Suddenly I was very, very worried. At 33 wks it is WAY to early for this baby, not to mention I have nothing ready yet.
Mr. W was not as concerned, and seemed mostly confused why it should be a big deal. He also had to go back into work for a conference call with Japan so me waiting until the afternoon to decide to call the dr made things a challenge. My mom said she'd come over right away to watch the boy. Fortunately she had no meetings scheduled that afternoon.
Once at L&D I was hooked up to a monitor and left to myself. After a time the nurse returned and asked me if I was having contractions. I said, "No. I don't think so. Well, I guess anything is possible." At which point she informed me that I was having contractions. So obviously I am unable to distingusih between fetal movement and contractions. At least none of them are bothering me; I haven't felt anything that feels labor-like. She also said the baby looks fine and that I had passed her NST. Apparently the 4 hour monitoring is used immediately after a fall, but since it had been over 24 hrs and I felt fine and had fetal movement I would not need such extensive monitoring. Yay!
She also checked my cervix and found it to be completely closed. After calling my dr to report on me he asked her to give me a Fetal Fibronectin test. Apparently it is a "glue" that keeps the baby in the uterus. If it is found outside the uterus between 22-35 weeks then that leak can indicate pre-term labor. After learning that my cervix was closed I felt fairly confident that I'd be fine. I receivd the results this morning which were negative which means that I can be "99.2% assured that [I] won't deliver in the next 2 weeks."
What a relief! But Now I am much more motivated to have Mr. W keep the boy occupied so I can rearrange the drawers in the nursery, unpack, and wash the baby clothes.
