First Baby Appointment

My SO and I had our first baby appointment yesterday. They basically just confirmed the pregnancy and said all of my symptoms seem normal and advised me on what to do until my next appointment on October 15th. I'll be 10 weeks at that point so I'm 5 weeks, 2 days now. I can't stop obsessing over the fear of miscarriage. I'm 21 and am in good health. Is the risk very likely or am I wasting my time stressing over it? I feel like a hypochondriac over every new feeling I have in my stomach or cramp I have and every time I go to the bathroom, I'm afraid I'll be bleeding. This is my first baby and I just want to do everything right and do the best I can for it to develop and grow into a healthy baby.
