Feeling stupid.

I have been in relationships for awhile ,but we haven't been on the best of terms. We broke up , and I started talking to my old high school friend. Well I slept with him more than once I don't regret it. I'm still seeing him his funny , nice , caring and the whole nine yards. I really like him ,but bad part I wasn't thinking and I didn't use protection. I'm 8 days late . I'm about be 21 and his 24 years old . We both have job ( we work together ). I'm just scared what if it's positive and he gets scared and leaves. IDK
