ovulation bleeding

Alison
Hi there.  So last week CD 9, 10, 11, 12 had HIGH on OPK.  Ran out of sticks so stopped testing. Anyway, since my ovulation day I've been bleeding.  I was pretty bummed because we are actively TTC.  Not heavy bleeding but definitely not spotting.  Also twinges of cramps on lower right side and pretty uncomfortable lower back pain.  This bleeding is very unusual for me (I did have an MC in December). Has anyone ever had a similar situation and/or gone on to be pregnant ?
