Hi BelaBrasil,
The publication at the bottom of this post explains what happens:

There is a second ovulation in the same cycle. It occurs at the end of the period. On day 5, estrogen has been low, and progesterone zero, for 10 days. The ovaries need to start making estrogens again, so the anterior pituitary gland signals them to start working, by increasing Luteinizing Hormone (LH). Once the anterior pituitary gland sees the estrogens, it stops making LH.
If the LH peak becomes very sharp, the ovaries may mistake it for the signal that starts an ovulation. That is normally a sharp LH peak on day 13 or 14, caused by the sharp drop in estrogens between day 11 and day 12.
So what to do about it? I don't really know. I think preventing an LH peak on day 5 may help. A simple way to do this is to start a low dose of PM earlier, on day 4, or even on day 1, and then increase PM very gently up to day 11. Something simple like forgetting a dose may cause an LH peak.
