LH lines

Amanda+2👱‍♀️👩& 2👼👼👼+🌈Due May `19
So on Monday I had a high fertility pop up on my clear blue advanced- and have had that blinking face ever since, but I noticed my darkest lines were on day 19& 20, now on day 23 and it's like the second line has disappeared... is this normal? Does it mean my cycle is done?
