I had my period on 16 april. had unprotected sex on 4th of may, took the morning after pil same day. it is now 27may still did not have period. i am worried did a pregnancy test 12 days after taking t?

Probably ok: the morning after pill is a megadose of hormones, and it can take your body some time to normalize. typically urine pregnancy test will become positive at the time of your expected next period. ( ~may 16 for you). take another pregnancy test now; if it is negative, i doubt there is pregnancy. but if your cycle does not return, go to your doctor
