Pregnant?

I'm only 10 days late, so normally I wouldn't panic.. Except my partner and I have been having sex often without any protection (he doesn't even pull out). I'm also worried because lately (for the past week) I've been randomly throwing up and then I'll feel fine for hours... Sometimes throwing up is preceded by some cramping in my lower abdomen. I have no taste for food what so ever. I do smoke weed daily and have been using it to combat some of this recent discomfort. However, usually I have a crave for it or enjoy the act/taste, where as now I'm repulsed by it even though it's the only thing that helps. I'm going to the doctor later today, but I'm stressing out and am just looking for some peace of mind.....
