False Alarm! I'm so mad!

I thought for SURE that last night was IT. Yesterday I felt really crummy all day- I had a headache nonstop and felt achy and tired and sluggish all day. Then last night around 10 pm I had to get up to use the bathroom literally every 20 minutes, so I could tell Hadley had dropped down lower. I started having painful cramps in my belly and what felt like contractions that would tighten up and make it hard to breathe. They weren't regular, they were pretty sporadic, but I was timing them. I timed contractions starting at midnight all the way until 6 am. I tried to sleep but kept waking up- I was terribly uncomfortable and still had a headache. Every time I woke up I would get a contraction. It was like my body wouldn't let me sleep. I thought, "this is it!!" and it was both scary and exciting. Around 6 am I fell asleep and woke up when Thom got up a few hours later. When I woke up the contractions were gone...the crampy pain was gone, and the headache was gone. Which I should be happy about...but I'm not! If I wasn't in labor then why did I have to suffer all night? What a cruel joke! Thom thinks it's pretty immanent and this was a warm up for the real deal. I sure hope so!!
