Is there a chance I could be pregnant?
Last period started 24th of January. Ovulated 7th or 8th of feb. Breasts started becoming very sore 4 days later. That was 10 days ago. Two days ago I started getting lower abdomin cramps on the right side along with major bloating. The feeling down there is as if I am having a heavy period. My breasts are still tender. Today would be day 28 of my cycle and I just experienced brown discharge. I had a blood pregnancy test yesterday morning. It came back negative. But I think maybe implantation just took place today. So is it possible to get a negative test and still be pregnant because implantation didn't happen until today?
