Should I have a faint line?

Hi I’m 7dp5dt and still getting stark negatives- not even a hint of a second line. Just wondering if it’s possible to still get a positive? Also my beta bloods are in 1 & 1/2 days time, can you still get a blood result confirming pregnancy if the tests don’t have a 2nd line on day of beta?
