My last period was June 16 to June21. It was not a normal period, it was light the whole time. For about 3 weeks now I have been feeling flutters in my lower abdomen, and my breast have been tender. Last week I had a pain in my left breast and it felt like one of my milk ducts was enlarged, so I massaged it and the pain subsided , but still tender. My breast are tender, heightened sense of smell, nausea in the morning and night, I haven't had much of an appetite. These are the same symptoms I had when I was pregnant with my first child. I have taken several HPT's and all of them say negative. Last pregnancy did not register on a home pregnancy test until I was 4 months prego? Could there be another reason for these symptoms?
