Do lines get darker nearer ovulation?

Sam

Hi ladies. I’m using one step ovulation strips. I ‘should’ ovulate around Sat/Sun. I’m testing twice a day at 11am and 8pm and so far they are completely negative with no test line at all. My question is should I start to get faint lines that get darker in the lead up to my peak or can I go from no line to a very dark/positive line? Sorry if that’s a daft question x
