Can you ovulate twice in one month??

Taylor

I took an ovulation test on day 11 and I got a positive and then I also got a positive on day 20. This month I am on my first round of clomid and also taking medication to lower my prolactin levels. Has anyone got two positive ovulation tests this far apart from one another?? I would greatly appreciate your responses.This whole process has been so stressful and depressing.
