I haven t had a periond in about 1 1/2 months. About a month ago I had a couple days of thicker reddish brown bleeding. I have had really tender breast for 3 weeks now, with bumps on my areolas as well as darkening of the areolas. Swollen sore, heavy feeling breast, with an increase in size about a half of cup. Mild cramps, and extreme fatigue, with light nausea, and dramatic mood swings. I took an at home pregnancy test and it was negative. I have had intercourse the past 3 days, all resulted in a bright red orange bleeding. Could I be pregnant, and if so, do I have anything to worry about with the bleeding?
