Second surge

Melanie

Can someone explain the multiple LH surge thing to me. Why does it happen? What does it mean, if anything? I got my peak reading cycle day 17 and it’s now cycle day 27 and I’m getting another peak reading. 10/11dpo ..not sure which one. I’m fairly new at this. Pregnancy test is negative. Period is due sometime between now and Friday. I range from a 27-30 day cycle.
