Ok so my fertile window started last Sunday. Monday I had a sharp pain on my left side. (I assume it was ovulation pains)

Wednesday I had similar pains on my right side.

Then on Saturday I had extreme pain on my right side that made me so sick I was afraid it was appendicitis (it was just severe ovulation pains). This also happened to be my predicted ovulation day on this app.

Now as I understand it, if you have ovulation pains it should only be on one side and it should only happen the one day. Am I wrong or is it possible I ovulated three times? Or could it be something else entirely?!
