Spotting before BFP?

Ali • Full-time student working on my RN-BSN while expecting baby number 1! Due July 2016! ❤️
AF is due today. Nothing yet. Have had random very light spotting this week. Anyone had similar experience and then gotten their BFP? Waiting a few days to test- don't want to get too excited if my period is just running late, but am secretly hoping like most of us! :)
