i was about the same week you are when i started to do the same thing, this was my second pregnancy, and i was induced the first time so i didnt know what i was going through, so i called my doctor and they had me go to the hospital and to make a long story short i ended up on bed rest through the remainder of my preg. I had a home montoring system and had to put an iv in my leg to help the contractions slow down. It was not fun at all. But if i were you i would called the doc. and maybe just drink lots of water and stay of you feet. Because being on bed rest and taking care of a little one is not fun either. Good luck , take it easy and try not to do so much lifting, i know its hard with a little one. I wish you all the best and i hope that you dont have to go through what i went through.
