Nervous about Pregnancy

So this is my first pregnancy and in the beginning after I found out I was pregnant, I was spotting a bit. But that has stopped, now all I feel is sick and I get cramps every now and then. I haven't been able to see a doctor yet and Im just nervous about the whole thing... according to the app Im 8wks 3dys and my first appt is on the 8th..... Any advice?
