I'm pregnant!

Just found out I was pregnant yesterday not sure of how far I am but my calculation should be that I'm only about 6 weeks. I just wanna know what's next? Should I immediately go to the hospital btw I'm 19 years old and I thought it was impossible for me to get pregnant I been trying for over a year now with my husband. Due to a missed period is how I found out I was pregnant. I've had nausea boob tenderness almost all the symptoms even diareha. Anyways I'm super excited to have a little baby on the way! ❤
