Thanks for the query.
Since you are on Day 24, there is no point in doing urinary pregnancy
test. It is more sensitive if done 1 week after missed period.
You can as well do blood beta HCG
levels now as it turns out to be positive from 24 days of pregnancy.
At 5th week you can get a transvaginal ultrasound
to visualize gestational sac
Wish you good luck,
