Bed rest...again?!?

I have been having contractions for a couple of weeks now, and finally had a Dr's appt on Tuesday so I could talk about what that means! Not thinking anything other than Braxton Hicks, I wasn't worried at all, they were just more annoying than anything. I was a little suprised and nervous then when my doctor seemed concerned, and asked me to start counting the contractions I was having each hour. Apparently with BH contractions, usually you might have a few and then they stop for awhile; but mine are continuous every hour, even waking me up at night! His warning limit was more than 4 per hour, 2 hours in a row...and he wanted me to come in on Friday (yesterday) to do an ffn test, meant to determine whether or not I might go into labor in the next 2 weeks. Well, we didn't quite make it to yesterday...as I was out with friends for dinner Thursday night, I started having contractions that were 10 minutes apart!!! This went on for over an hour, so I called Eric and told him he'd better meet me at the hospital. (Fortunately, I had just recently "trained" him that he HAD to keep his phone on and by him at ALL TIMES now! =) Jake was REALLY upset that he didn't get to go to the hospital, and called us every 10 minutes we were there. He was just really worried...poor guy! Apparently he ended up bombing a test yesterday that he wasn't able to concentrate on studying for...hopefully a chat with his teacher will straighten things out!
It was a pretty scary night, but even with all of the contractions, my cervix had NOT progressed, and was still well within the normal range for being 28 weeks. The hospital also did the ffn test, which came out negative, so even through all the contractions, this baby was staying put!! The funniest part of the whole night was that the monitor I was hooked up to let us hear EVERY movement the baby was making, and just as I have been saying for weeks, this kid does NOT STOP!!! Each time the nurses came in they would laugh, because he was making such a racket in there! If two minutes went by without him moving, all I would have to say was "maybe NOW he fell asleep"-and I would get a swift kick or elbow to prove me wrong!
They did let us go home after about 4 hours, because the contractions had slowed down and become irregular enough that they felt we weren't in any danger.
Yesterday I went to my dr, knowing that he was going to try to take me off work for the remainder of my pregnancy. I had a compromise that I wanted to try out on him-I would take the medication and do the "modified" bed rest, but could we please just take it a week at a time to see how I was doing? I fortunately have the ability to work from home, but that probably wouldn't fly for the next 12 weeks...so he agreed to taking me out for the next 2 weeks and then evaluating me from there. He basically told me that I have an "irritable" uterus, and that I needed to be on medication to calm it down and hopefully stop the contractions. Between that and the doing NOTHING (which OMG...I have so much to do!!), just in the last 24 hours I've seen a big difference in the amount of contractions.
The biggest concern is that I had this with Jake as well, but it happened much further along-he was only 4 weeks early. Since I have a history of pre-term labor, my doctor will be extra cautious with this one...as will I!! We definitely don't want a 2 lb baby that has to stay in the hospital for weeks-although the size he might be full-term does scare me a bit too!
