Hi!
Good day.
I appreciate your concern for the possibility of
pregnancy from Pre-ejaculatory fluid.
Yes, it is quite possible.
The pre-ejaculatory fluid contains sufficient number of active and motile sperms which can fertilize the egg and hence pregnancy can occur.
Since you have taken the post coital emergency
contraceptive pills immediately, these pills are effective only in 90% of the users if used within 72 hours following unprotected penetrative sex.
Regarding the side effects of the pills, it may not be seen in all the users.
To know their efficacy, best thing is get the pregnancy test done on early morning urine
pregnancy tests if your menses get delayed (with or without the symptoms of brownish discharge, lower abdominal cramps, breast soreness, etc) to rule out pregnancy.
Hope to have answered your query.
Take care and convince your partner to use the condom as it not only prevents unwanted pregnancy but also the
sexually transmitted disease.
