Scared

Hey sooo I don't really know what to do. My boyfriend wants to break my virginty I'm over 18 and done with school and I want to do it with him but still I'm scared 
1. I don't like pain and don't know what to expect the first time 
2. I'm moving and first he said he don't want to do the distance thing but now he's suddenly oky with it 
3. I'm on the pille and will be using a condom but I still have this fear of getting preggers  
What do you guys think I should do ?
