Drink lots of water, rest & call ur OB. Definitely time them as well.
Time them! I had back labor with my first!! I have to say though, it wasn't as bad for me as the tummy contractions, and was a lot easier to deal with and easier to mistake for normal pregnancy pain!! Just start timing and see what happens....if the pain gets closer together go to l&d!
I would time them...I didn't hv back labor with first but did with second...you never know! Good luck!
