Welcome to healthcare magic
4 days delay without any symptoms of early pregnancy
such as nausea
, giddiness, breast fullness may stand a low chance to be actual pregnancy.
The delay may not be due to pregnancy.urine tests that are done at home occasionally take time to come positive , blood testing that is beta HCG
would clear your doubts without any further delay but at some cost.
You can repeat the urine test in another 3-5 days to feel relieved in case you want to avoid the blood test.
Hope this is helpful
