You should call your OB Nurse or your OB Doctor immediately whenever you're experiencing such situations. I'm wishing you tons of baby dust and that everything is okay. Try putting headphones on your stomach and play the music loud to see if you can startle baby. Also, try shining a flashlight on your stomach . . . another thing I used to do is push my prego stomach to try encourage baby to move. Please call your OB/nurse or doctor, hon.
Do not wait to call. Go to the e.r. right now.
