Pregnant?

According to Glow I should have ovulated around 4/29 (cd 10) but the following day up until today I have experienced cramping on my right side and some thick milky discharge with some stringy clear as well.  I am not due to start my period until 5/12 and am usually pretty on time (never very early or late to start my period).  I have a 24-25 day cycle.  Is there a possibility I ovulated a few days late?  I do not use any tests to track my ovulation.  My husband and I had sex on Friday so I'm assuming it is too soon to "feel" pregnant.  Thoughts?  :)
