i took the morning after pills but is any chance?

Hi,
Welcome to ehealthforum,
Pre-cum/pre-ejaculatory fluid is also known to contain sperms in it. If pre-cum or semen has come in contact with vagina, pregnancy can result (especially if you are during your fertile days at the time of sexual contact). The emergency contraceptive pills (ECP) work in preventing pregnancy if taken within 24-48 hours of the unprotected intercourse. Withdrawal bleeding usually occurs after 5-7 days of taking the ECP indicating that it has worked (it may not occur if taken close to your period time). Since the ECP contains high doses of hormones, these can disrupt normal period and hormonal pattern and cause delay in normal periods. Wait and watch for your next periods/withdrawal bleeding. Consider visiting your doctor/gynecologist for further evaluation and assistance if chances of pregnancy are suspected, or if you develop any new symptoms suggestive of pregnancy, or if you do not get your periods within 10 days of expected period dates.
If pregnancy gets ruled out, and if you intend to remain sexually active, consider getting started on suitable regular birth control measures to be protected (after your periods). Be regular with birth control use as instructed. Avoid having unprotected sexual contact and repeat use of ECP.
Take care.

I did not experience any withdrawal bleeding, it's been 8 days after what happened. Can I know if the absence of withdrawal bleeding indicates that I might be pregnant (due to the implantantation or does it also indicate that I might not be pregnant?
