Mixed feels

Abigail • 20 college student, not trying to baby. I have a happy healthy relationship, and I need to get through my classes first
I recently had a small pregnancy scare. I have a committed and loving relationship, I am 20 years old, and am very happy with how things are going. But once I found out I might be expecting I freaked out. After a few days I calmed down and put things together and now that I know I'm not expecting I am kind of I guess sad. The idea was a nice one, but I know it's not the right time. Has anyone else in my position felt this way?
