Help!!!

Kayla

I'm at a loss! TTC for just shy of a year now. Previously had a IUD in for 7 years. Was placed on Clomid for the next 3 months on days 3-7. Also told to take ovualtion tests daily starting on CD10. This is my first round of Clomid and I've taken the tests daily of a morning usually. Should they gradually be getting darker or is it just one day it will be positive. With taking the Clomid will I ovulate early or around the predicted date???
