thanks for using health care magic.
the best option of preventing a pregnancy
after an exposure is the use of emergency contraceptive
pills or the morning after pill which is very effective if taken within the following 72 hours. this method prevents the pregnancy from occurring and failure to do so may require termination of pregnancy later if you fall pregnant and do not wish to keep the pregnancy. Emergency contraception
thus is safe and a better option to the termination of a pregnancy.
and clavulanic acid
will not alter the effect of the contraceptive and you could take your contraceptive if you are still within the 72 hour limit.
Best regards and hope this helps you.
