How do I tell best friend that I'm pregnant?

Chelsey

So my best friend has been TTC for the past 3 years but keeps having miscarriages. They decided they were not going to seek help and stop trying all together, even though I know she still wants another baby so badly. Well I just found out that I am pregnant with baby #2 but I have no idea how I'm going to tell her. I know she will be excited for me but I also know it will crush her. We're going camping together this weekend and she'll know something's up since I won't be drinking. How do I approach this? Any ideas on how I should tell her?
