Can you ovulate twice in a cycle?

Hi All, I have already ovulated last Saturday, which was 3 days ago. My temps are up since then and I had got +ve OPK on Saturday. For those 2 days i was getting ovulation cramps on my right side. We BD Friday and Sunday and covered the window. Since today morning I am getting cramps on my right side again (same as my ovulation cramps). Is it possible that I am ovulating again??
