Quick answer

Test from the first day your period is late, or at least 21 days after unprotected sex if your cycle is irregular or you are not sure. Testing earlier can miss a pregnancy.

How it works

Home tests detect the pregnancy hormone hCG in urine. The NHS advises testing from the first day of a missed period, or at least 21 days after unprotected sex.^[src] We show whichever comes first based on your cycle.

A pharmacy test costs from ₱64.75 and needs no prescription. If the sex was within the last 5 days, the more urgent step is to talk to a doctor about emergency options.
