Don’t know what to title this...

I just recently found out I am pregnant. I couldn’t be more excited and neither could my loving fiancé. Last night he started talking to the baby, even though it can’t hear us yet. However I’m honestly scared. I’ve been feeling kind of crampy lately and I’m hoping it’s just because I’m constipated. I keep having this dream that I’m gonna be a horrible mom. Is this a fear that everyone goes through?
