My fiance and i have been haviogn unprotected sex a couple of times. I know tha was a mistake becasue my period has been irregular for since i was 12 years old. My doctors put me on medicine and then i get periods but after i get off they stop. NOW i have a milky white substance coming out of my breast but every pregnancy test i take it comes out negative. I am tired alot, gaining weight, eating habits has change and feet are swollen, what should i do? ANd yes still no period havent had one since may 2006. 8-|
