Should I go in?

Britney • Isaiah William 9/9/15! ♡♡

What do you guys think? I went into L&D yesterday morning due to pain and contractions and found out that I am 4cm and 75% effaced. I don't wanna go back in if it's nothing.. the contractions are tolerable but still a little painful. I also have constant back pain and a little crampyness right at my pubic hair line. I'm 40 weeks tomorrow.

Oh and the like 45 minute interval was from my husband and I going for a walk.
