First Time Carrying?

Shy

I've been on depo for the last 10 years and had one Miscarriage now I'm pregnant again on depo and we're keeping baby but what are my risks with the birth control in my body still? Should I get excited yet without know how it has affected baby? Am I just going to lose it because of this? (My next Depo shot was scheduled two weeks after I discover I was pregnant and without having a period I have no idea how far along I am -not showing- but my family carries small and don't usually start showing until about 6 months. My first appointment is June 4th
