Late period

So hubby and I used the pull out method for the first time ever two weeks ago..it just so happened it was my most fertile day. Hubby said he "thinks he pulled out in time". I'm now two days late for my period, and having a lot of milky discharge. I was cramping earlier and swore I was about to start my period. Then the cramps stopped and I never got it... I guess just looking for some opinions!
