Any idea why you have 2? I should have ovulated around the 27th
No idea about your particular case---but sometimes I get that right in the middle of my luteal phase, and I think it's the result of a secondary estrogen surge. I read that---if my memory serves---in Taking Charge of Your Fertility. Is this cm coinciding with a waking temperature dip? It always would, for me, and I think that's another signal the estrogen surge is happening.
