Just need some insight?

Cycle day 63🥺 I’m 29 days late.. I usually have regular cycles monthly. I get a pelvic scan in a little over a week from now.. but was told to keep taking at home tests to see if they turn positive. I took this at night, but I feel like if I was it would be positive at night too yeah??

Should I keep testing, if so how long should I wait to test again?
