So I lost 11 lbs while I was in Africa and that's how I figured I may have been pregnant. I am now 16 weeks and am back at my normal weight. I weigh less than I did before I went to Africa but that is mainly due to muscle loss since I used to run much more than I do now. Has anyone else been in this situation? I have a little tummy, not much, but don't really weigh any different.
