Had unsafe sex n took emergency contraceptive pill. 1 month later got hcg 1.5 -ive blood test. nw 20 days passed since due period date. am i pregnant?

Unlikely: Unless u had unprotected intercourse again. 1.5 is below most cutoff ranges. Nevertheless, try a urine pregnancy test. They are cheap and will ease your mind. Good luck.

1 out of 8 chance: If emergency contraception is taken as directed, it can significantly decrease the chance that you will get pregnant. About 7 out of every 8 women who would have gotten pregnant will not become pregnant. 1 out of 8 will. Hcg <5 (depending on the lab) is a neg test. If you are late on your period you need to repeat the hcg.
