Help! Anyone with cramping and spotting after BFP?!

hailey • TTC after a 9 wk mc in 2013 - been with DH x 7 yrs - just found out we are pregnant on 4/1! Be sticky baby!!!! ❤❤❤
I'm 15 DPO and AF due today.  I honestly feel like she is on her way.  Had some light spotting last night and today.  I've retested like a crazy woman but haven't noticed it getting darker.  I think I'm losing my little bean already!  :((.  Help!
