First of all, you did unprotected sex near ovulation time or close to fertile period. Taking I-pill within 24-48 hrs gives protection near about 85%.
You should undergo one home pregnancy
test at the earliest & one blood test
for beta HCG
to confirm or exclude pregnancy. One TVS scan can be done to confirm intrauterine pregnancy.
In case of positive pregnancy test, you should consult with your gynecologist to abort medically. Taking unnecessary MTP pill can cause uncontrolled excessive vaginal bleeding
and other side effects. In case of failed medical abortion
, you may need to undergo surgical method of abortion (D & C).
Be well & practice protected sex.
