Hi lizzybee.
Im in the same situation right now. I’ve only just finished my period a week ago (it was also light and a bit different from normal) and now am feeling sick most of the time and cannot eat alot of foods. I am pretty certian I am pregnant (as I have had these symptoms before) but unfortunatly I think the only thing we can do is wait until we miss a period to take the test. No one can say for certain that you are or are not. perhaps you should talk to your doctor?
