Opk is this normal

Hi since cd19 until today cd24 my opk has not gotten any lighter or darker. And I test 3 to 4 times a day with both digital and strip. Is it normal to see no change what's so ever. My cycle is usually 30 days. Going crazy and getting mad as now I just feel like I won't be ovulating this month. Start opk at around cd8 was lighter started getting darker as days went on and around cd19 just stopped darling and has stayed like this.

Sorry cd19 just looks like that because it is 5 days old. Please give me some advice
