question if you can answer it :).

So I have pain near my hip bone on my left side.  4 weeks 5 days.  Normally pregnancy symptoms otherwise.  It's pretty contestant hurts a bit more when I stretch.  Doctors appointment Tuesday... anything idea what it might be?  I know it could be ectopic pregnancy but I'm hoping someone has had something similar and it turned out to be something mild :). Optimism will get me through the weekend lol.  Hoping this is my rainbow baby.
