Worried

Hello, I’m currently 19 weeks pregnant with a little girl. This is my first pregnancy and honestly I haven’t enjoyed my pregnancy a whole lot. Due to the fact that I’m constantly worried that I might lose my little girl. I haven’t had any bleeding, but I’ve had some cramp like pain, and some stabbing pain. Not constantly and not enough to keep me hunched over. Can someone help me figure out why I’m feeling this way and how I can help myself to not worry so much about losing my little girl. She is something I have prayed for and I’m so scared even though I have no reason to be.
