I am experiencing the following symptoms during my early pregnancy: headaches, vaginal pains (no bleeding or discharge, similar pains as with my normal periods), bloat. are all of these normal?

Yes: Pregnancy involves huge changes in a mothers body. Hormonal fluctuation, cardiovascular changes, even muscle changes as the uterus stretches and the vaginal/pelvic are prepares for the birth process. There are a variety of websites, as well as books outlining specific things to expect at each phase. See a Dr for bleeding, severe cramps, high blood pressure/ pounding headaches, or fever above 102.
