Hi, I have been trying to conceive for the past 2 years and still there has not been any luck but last month when it was time for my period it began 3/10 and it was brown and not heavy at all then I began to bleed but it wasn't heavy so for the next four days I began to spot light brown until it ended.Now I have taken a pregnancy test that was negative,but I feel very tired in the morning I can just awaken and I want to return back to bed, I have very sore breast and I have to use the bathroom a lot more.Could I be pregnant and not know because I have a friend who was and she bleed the whole nine months and my sister in law is now and she bleed the same ways for four months then it just stop and she was also pregnant .
