I am on number 5 too and due july 10th and i have no idea too! lol

last night I had the period pains too and stronger braxton hicks and my back is also aching and lots of bm so i thought it might be the start of something , but no i still wake up pregnant.

i remember though the real deal contractions that you can no longer ly down for and that make you go "oh no why am i doing this again!"

so i don't know but i know what your going thru, i had some nesting earlier on but i can hardly move now.

best of luck hope you go into labour soon
