H M.! First...a little about me. I am a SAHM to 3 kids...11 yrs (in Nov), 8, and 3 (this month). My first was induced 4 days early because of preeclampsia. The second came on her own 3 days early. And the third was induced 9 days late. I tell you this all as part of my answer to your question.
There is no way (as many have already stated) to be able to judge when you will go into labor on your own, if at all. It is normal with first pregnancies to dilate and the baby move down a month prior to the due date. In subsequent pregnancies, it is normal to not dilate at all and the baby to not move down at all until hours or even minutes prior to labor starting. Now, how that relates to what I told you about my kids. My oldest who was induced 4 days early....I was 3cm dilated and she was all the way down approximately one month before she came. How frustrating that was!! I wanted to see her now!! The middle child, I had been to the doctor about 3 days before and he had stripped the membranes in an effort to move her along. I was not dilated at all! 100% effaced...but no dilation. How disappointing! But at 3 am, 3 days early, she decided to come. When I got to the hospital at 6, I was 6 cm. With the third, there was no dilation...I was a week over due...I was begging the doctor to induce me. He finally agreed at 9 days late. There was no dilation...only effacement.
Moral of the story....like everyone else said...you probably still have the rest of the month that is supposed to be left. I know it is exciting to hear that you are dilated. But the baby will come when he/she is ready to come.
Congratulations on the new addition! It is a wonderful time. Best of luck!
