Contractions... is this it?

So I have been having contractions (real painful ones, not just tightening) since about noon today. At least that's when I began somewhat timing them. They have been fairly consistent at 20 or so minutes apart. I have had a few periods where there are none, so that makes me second guess myself. But I woke up this morning feeling different, so I truly think we will have a baby by Monday at the latest. What I am really hoping for is a baby tomorrow. I will update if/when we leave for the hospital!

Oh another thing, I always say my labor with Leah was 41 hours because I began with contractions like this, 20 or so minutes apart, Sunday night at 8pm and she wasn't born until Tuesday at 1:30pm. At what point do you consider that labor begins? Did I really have a 41 hour labor, because that seems insane. I was only 3cm when I got to the hospital at 11pm on Monday night. (Just had to pause for a contraction at 8:06pm) So do I count labor as begun with this one at noon? I guess if I go to the hospital and they send me home, it counts as false labor. They almost sent me home with Leah because the contractions weren't regular enough, but then they took pity and let me have the epidural so I could get SOME sleep.

I am doubting there will be much sleep tonight, especially since my mom's plane arrives at midnight. I am so happy she is coming I cannot tell you. Here's hoping that I update sometime tonight that we are going to the hospital!
