The start of the end?

Heath • Pregnant with second baby. Daughter is 2. Married for 5 years.
Last night, I was a mess! I felt so vulnerable and my body had aches like I haven't had yet during my pregnancy. My back started hurting and even all 8-10 times I peed, hurt because of pressure. I thought my body must be getting ready for labor (I am 40+2). Then I got the chills so badly. I have been pretty warm natured this pregnancy. My husband held me to try to warm me but it took him plus a heating bad to help. Then I noticed some of the Braxton hicks felt different and based on what I had been told they felt more like mild contractions. My baby had been active for over 4 hours straight (unusual for her) so I thought maybe her adrenaline had started that is supposed to help her through the process of labor. I timed two of the contractions and they were lasting 30 seconds 8 minutes apart. So instead of timing more I decided to sleep (around 5 or 6am at this point) because I thought labor was starting. Well it is now 12:30pm and nothing. I feel pretty good. I want baby out! Bring back the contractions! I really am hoping once I get moving again they start up again! I am hoping this is the beginning of the end!
