My last menstration was on 5/22/2006. I had sex on 6/3/2006. I have not had my period since.

I have been diagnosed with polycystic ovarian syndrome, so I wasn't worried when my period didn't come in June. However, for the past few weeks I have had tender breasts, frequent urination, a little cramping, and a weight gain of 5 lbs. I've also had an increase in white milky discharge and I have been very gassy.

I have been trying to get pregnant but I don't want to take a pregnancy test because everytime I do they come back negative.

Some of the symptoms have begun to subside.
Is it possible to have pre-menstral symptoms and not have a period?
