You had unprotected intercourse
in fertile period. You should have taken emergency contraceptive pill
or two tablets of Mala D within 72 hours of unprotected intercourse. Now you have to wait for the menses to appear. If they appear, start Mala D tablets from second day of the menses.
If menses do not come, get your urine pregnancy
test or/and ultrasonography
done for detection of pregnancy 8-10 days after missed period. Tests done earlier may be inconclusive.
If you are pregnant and do not want the pregnancy you can get aborted by medicines. Report to your Gynaecologist for that.
, you can start the Mala D tablets immediately.
I hope this answers your query.
