Getting Nervous/Scared

At 34 weeks everything scares me now. I'm always on edge as a first time mom. If I have an ache/pain/swell or anything I get concerned. (TMI)I felt sick today and it ended up that I had diarrhea really bad. Even that scared me! It's a terrifying thing as I get closer. I'm constantly worried that the baby is coming or that something might happen to me that would hurt the baby. I feel so protective already!
