I agree it sounds like ovulation approaching. I don't want to sound like a "wise old woman" but remember to relax around this time so you don't delay ovulation. I am 100% certain that's what I did to myself when I had my extra l-o-n-g cycle that nearly drove me to drink. Looking back at it now and on my FF chart, it really looks like my body was trying and trying to ovulate as I had all the signs and symptoms more than once and eventually, when I gave up worrying, I ovulated.
Relax, exercise and have a night out with your friends. Good luck.
