Request for Prayer

I just wanted to pop on quick and ask for every one's prayers again. Many of you know my history with early deliveries...34, 36, then 38 weeks gestational age. So, this has also been something the doctors have mentioned more than once....the need to make it to at least 36 weeks with this pregnancy. I am now just about at 34 weeks....and I woke up this morning having 'different' contractions than usual. I've been having painless contractions up 'til now. This morning, I woke up around 5 or 6 with some contractions coinciding with a back ache, which for me is the type of 'labor' I've always had. I had these off and on all day....nothing terribly painful, but concerning all the same. So, if you all could just keep me in your prayers and add this to it that would be great. I know God has a perfect plan...I just don't know what it is! My mind can run away with me and of course I'm always imagining the worst-case scenario....We don't want to have a baby this early for obvious reasons, but we also know that God has taken care of every one of our children, even though they were 'early'. So the struggle is just having peace, knowing that we can trust Him (which we do know) while also being cautious and knowing when to call the doctor, etc. You would think I would know it all by now after having 3 kids, but I do not. There is always something that I don't remember, that I'm unsure about, whatever. So just knowing that I have all of you out there praying for me and my family, and a safe delivery whenever it happens helps so much. And of course going to the source of comfort, Christ Himself, gives me that peace. Thanks to everyone who is praying for us...we love you all, and look forward to letting you all know when this dear child arrives.
