Preterm labor!

This morning I was at work and I started having sharp pains in my lower stomach. (Felt like I had to go to the bathroom extremely bad.) They would last about two minutes and then ease off. This happened approximately every 10 or 11 minutes. My boss sent me home. I called the doctor, she told me to lay down rest and drink plenty of water. They stopped, then about 4 hours later it happened again. I just laid back down, and started drinking more water. And they eased off. What are my chances of going full term? I'm probably over thinking this. Lol. Just need some peace at mind.
