Well cramping can be normal in any part of pregnancy. However if they intensify or you notice any spotting, go ahead to the ER. Better safe than sorry in my opinion. I always minimize things, but better to be overly cautious sometimes. Even if they don't intensify but remain annoying if any little part of you thinks you need to be checked out, just go. Your dr will be happy you did:) Everything is probably A-ok, but just to ease your mind you know...Hang in there and congrats on your new addition!
