Light and the end of the tunnel?!

Jessica
Hey ladies. Okay Feb 23rd I had a D&C and last Tuesday I was due for my period after... I didn't get it so I took a test well 3 and they all had extremely faint lines... That Friday I thought I got what would be my period until this past Tuesday... But have kept having these symptoms I had during my first pregnancy... I just took a test today and two pink lines only darker today! Can anyone shed light to this? 
P.S the line in person is pink it looks clear in the photo only :)
