If they checked u Tuesday then u may have spotting from the exam. I had the same thing as well. Now if it becomes like a heavy period then u need to go to the hospital.
I was having the same problem and I am due the 15th with my second. I went to L & D and got checked. They said I was dehydrated which can cause cramps like a period or contractions. They told me yesterday to drink lots of water, lay on ur left side, try a warm bath and lay down. If they stop then it was just like Braxton hicks. This is just what they told me.
