I was leaning on my left side while on the couch (not completely laid down). Luckily, they've stopped. I wouldn't have worried except that they continued coming along regularly--no pain, though. No bleeding, either. Nothing out of the usual so I figured if I'm going into labor this early (I'm only 32 weeks along) then I'll be feeling harder contractions coming along any time now. They subsidded and I've only felt an occasional one since that night. Keep in mind that we had that horrible day with my dog, too. I was so freaked out and upset!
Thanks again, Robin. You are so good to always post what you know to people on here.
