Ovulation Testing - help!

Beth

This is my second month trying to ovulation test. I'm a bit concerned as my tests just aren't picking up any LH increases. Last month I thought it may be cheap tests so this month I bought more expensive ones. I understand that I'm not at peak yet but my levels are going down? It says that I'm in my fertile period and that it should be going up?

Does anyone have any tips? What time of day is best to test?

Please be kind as I'm new to this. 😊
