Go for it!
In my experience in undergrad and graduate engineering, civil, biomedical, and mechanical tend to attract more females than other disciplines (15 to 20 percent in these fields, about 5 in electrical, computer, etc.). There is a huge effort to get more women interested in engineering, and in fact the lack of women in engineering positions is one of the biggest complaints companies have. If you choose to be an engineer, your gender will make it easier for you to be hired for the same reason. There are also professional societies, such as Society for Women Engineers (SWE), that do great things to promote women in the field. If you have concerns about social issues, don't worry--you won't be stereotyped as a nerd. You get quite a bit of respect when you tell people what your major is.
Anyway, I hope you find out more about this and that you make the best decision for yourself. Who knows--perhaps you might be a colleague someday.
