Next steps ??

My last regular period was jan 17 - 21  my next predicted period was feb 14 - 18. After being 11 days late my period started (feb 25 - 1) but it was not like one of my normal periods , my first 2 days were not as heavy as my usually period but was not light enough to be spotting. The last 3 days were super super light, real close to spotting. I was exsperiencing some early pregnancy syptoms so I thought I might be preagnat but now I'm not sure . Should I be concerned?
