Question. I just bought what feels like my 100 box of tests. I’ve heard different things about this but need better clarification. I want to know if I should use the digital reader from the box from my last cycle on my new test strips or should I use the brand new one in the new box of OPK’s I just bought today. Confused. Some ladies have said to keep using the same one but others said no. Thoughts would be great. I start testing tomorrow. Thanks ladies
