Can I or can't I be pregnant? My period is due today. When my period starts, I get a full flow on day 1 bright red. Today, I woke up and wiped and it was a brown discharge like old blood. I had a pad on and no further discharge all day. This has never happened. Could it be pregnancy. I did a test a few days ago and it came up as no pregnant on the Frist Response. Is this implementation spotting? I finished all my test. If its implementation, how long do I have to wait to test? Any one experienced implementation bleeding instead of a period and test came out negative and then later on it came out as positive?
