My body is up to something

I went in for my first prostoglandin gel application this morning. before it began I was still only 1 centimeter dilated and 50 percent effaced. I had a really rough rest of the day, It felt like the worst crampy period ever, intermixed with some serious contractions. When I called to go back in for second application at 3, they were too busy, so I didn't go back in until 6:30 When i finally got hooked up, they couldn't do the gel this evening because I was having too many contractions- about 1 every two minutes or so per the monitor so they sent me home. I am still only 1-1.5 cm dilated but now 80 percent effaced. I feel slightly better in that I wasn't crazy in the afternoon- I was actually having painful contractions and it wasn't all in my head. I have to go back in the morning.
