Starting Nov.13/11 I've been having regular intercourse with my boyfriend. We use the pull out method and last month I thought I was pregnant. I had so many symptoms even spotting but did get my period after a week but it started brownish for 3 days and then was a normal red for 5 more. During this time I was really light. My next period which came a week early also started brownish and again lasted a little longer but again super light that I barely needed to wear anything. But this time my stomach has been bloated as if I am still on my period and it ended 4 days ago. Now I have been discharging a white non odorless fluid and my breasts are tender and the area around the nipples are darker. I still have lower back pain. Is there a possibility I am pregnant?
