Double LH surge with Pic, never happened before.

Lisette
I had a double LH surge this month for the first time. I normally have a pos opk on cd 12 and my pos usually lasts for 2-3 days so I'll have pos opk on cd 12, 13 & 14 but this month I got my pos on cd 13 and I had light O pains in the middle of the night (cd 12 night to cd 13 morning) but by the evening of cd 13 it was negative again, I also tested cd 14 & 15 neg, I was disappointed. I thought I missed the boat. Well this morning I woke up (cd 16) and felt strong mittleschmerz (I get them every month) so on a whim I tested at 2pm. Positive smiley face opk. Kept getting O pains and tested again at 5:30 and another positive with lines even darker than earlier. I've read that you can have a double peak surge. I don't know if it means I will release two eggs this month or that my egg wasn't big enough  so  it was a false start and I will only release one.
