Yesterday I took two pregnancy tests in the afternoon and night and both were very faint positives. Af was due the 23 and nothing yet I was cramping a week prior to O day which was the 12th so Im 13 dpo today. Took another pregnancy test with FMU & negative.. I started spotting brown discharge last night enough for me to wear a panty liner... is this a positive sign? Shouldnt my pregnancy tests get darker? Should I just wait to test again? Maybe tonight?
