Was having regular periods. Trying for a baby. My last period was on nov29. Today am havng brown discharge. 2 days back took pregnancy test but negative. Am I pregnant?

How many day cycle ?
How many days are you past the date of period ( how late are you)

You need to be at least 10 days ( 14 is better) days past your period to test.

Then you need to test with the first urine of the morning ? Did you do that ?
