Had Unprotected Sex On January 30th. On February 21st I

Had unprotected sex on January 30th. On February 21st I had some weird discharge with some brownish/reddish blood streak inside. Than wiped and nothing for the rest of the night. Two days later, had cramps and really light blood. Was never constant. Never had a flow. Was never heavy. Only colors I had were brown discharge or a really light pink. Only had a dark red for an hour and when I wiped than nothing. Spotted for 2 days than the third I only had brown when I wiped. Never needed a pad with any of the days . Spotting was on the 21st, but my period was due the 26th. And I never got it. Took a pregnancy test 2 days after spotting stopped. Said negative. Had symptoms. Etc. is it too early ???
