Yay!! This is my first cycle using them, and I took my first one yesterday but it was negative. The test line was there but it wasn't nearly as dark as the control line... but the one I took today was MUCH darker than the control line!! I got so excited, you'd think I'd gotten a BFP or something!! *lol* My temp went up this morning too and I had a feeling it was getting close to O time. Hopefully it works!!
