implantation or early period?

Lisa
Just went to the bathroom and I noticed some reddish spotting. I think I'm 10dpo period due 3/19.  My period is typically 30ish days but it's come as early as 26. So I guess I just wait and see if this becomes a period... I am feeling pretty crampy today also and I don't normally get cramps before my period. Here's hoping it's not my period!  Do you think I should take a pregnancy test in the morning?  Or would it be too early if it is implantation bleeding?  Thanks!
