35 weeks today!

So I'm 35 weeks today and this is my third baby but it's been 4 years so dont remember must from last time. I been hurting in my back some today and been having bh for awhile but thinking I might actually be having some real contractions but not unbearable or regular yet. I got to ob tomorrow to get another growth scan and get check yo see if I'm dilated any. I have gd and when they scanned her two weeks ago she was 5lbs and 3 oz. Cant wait to go tomorrow!
