Your symptoms could be due to anything, including pregnancy, although most pregnant women don't experience pregnancy-induced symptoms until about 2 weeks after conception (takes awhile for the embryo to implant and HCG levels to rise to appreciable levels).
Is the discharge spontaneous or only happen if you squeeze your nipples? Any odor to the discharge and does the discharge come from one or both nipples?
Far as the discharge its both spontaneous thats when i first seen it and sometimes when me or my husband squeeze them. No odor and yes from both nipples. For about 3weeks now my sense of smell have been off, im smelling things that is not there and no one else can smell it.
Unfortunately there is no way to know if symptoms are caused by pregnancy until a pregnancy test is taken. Good luck.
