Ovulation test question

I'm confused.. I took the clearblue ovulation test on Monday and it came out with a high fertility smiley, I took it again on Tuesday and same thing high fertility, today was different and I got a low fertility circle... Does that mean that I shouldn't test the rest of this week? I have been testing since Monday at the exact same time which is at 5:50pm. I did have sex with my husband Monday and Tuesday. Should I just continue to have sex the rest of this week regardless of the test :(
