What Causes Abnormal Menstruation And Vaginal Wetness?

Hi. My husband and I have been trying to conceive. He thinks I am pregnant because my vaginal fluid tastes and smells sweet all of a sudden. My boobs have gotten heavier and have bluish veins all through them. I had a period but not like normal with no blood clots. Also it s like I get wet all of a sudden for no reason. Are these signs of pregnancy?
