frustrated!!!

I can't wait until this pregnancy is over!!! I went to the hospital early Tuesday morning about 1 am with strong contractions only to be sent home about 3 hours later b/c everything slowed down and I wasn't dialting pass a 2. Today I was suppose to have an appointment at 10:30. I woke up at 5am with contractions about 5 min apart. By about 9:30 they got stronger and were about 3 min apart. I called the doc to see if she wanted me to keep my appointment or come in ealier, etc. They told me just to go over to the hospital. After 2 1/2 hours, I got sent home again b.c I wasn't progessing and contractions had almost completely stopped and still a 2. Discharge instructions were to make an appointment for early next week to discuss options.
I have an appointment on monday (if I am still pregnant).
I am due saturday and I am miserable!! My back is killing me and I can't hardly sleep and have been extremely nauseated and thowing up just about everything I eat.
I thought for sure I would've had him by now!!! I am so over being pregnant!!!!! I don't know, I am just venting!!!!
Just keep us in your prayers!!!!
