I can tell when I'm ovulating by my Smell!
Funny ha but true when you ovulate you end up with wet underwear and a distinct smell coming from your underwear and pants you are wearing. For a while I was wondering what that scent was then finally figured it out. I have 3 boys and I'm TTC for my little girl now for over 2 years now. Good luck to you all and Baby Dust to all of us!
