Cramps

The <a href="https://play.google.com/store/apps/details?id=com.glow.android.baby">baby app</a> says im about 5weeks along, starting yesterday i had some cramping around the lower abdominal area & sometimes the sides. I looked it up and it said it could be ectopic pregnancy, i have the cramping, bloating but no bleeding. Could it possibly just be the growing pains since this is my second pregnancy? I'm waiting for the doctor to call me back when she's available but I'm hoping y'all can ease my mind a little bit.
