Having trouble with OPKs

Nina

Hi girls this is my first time using OPKs and am finding it hard as it is the stick tests from Boots. Have been testing for the last 5/6 days and have gotten faint lines on instructions says that means negative. However today line was dark pls tell me if this is positive and I am ovulating soon or if I am not yet ...

And any other advice on OPKs and ttc more than welcome!!! ❤️😘
