Hi,
Thanks for posting in HCM.
I have read your description and understand your concern.
Chances of getting pregnant by sperms present in
pre-ejaculate fluid is very less.
Also, you need not worry much about it as you have taken
emergency contraceptive pill within the time it needs to be taken.
But since you had intercourse after taking pills, you are at risk of getting pregnant as it is advised to use adequate protection like condom and spermicides after taking pills until you get withdrawal bleeding. Some of the individuals would experience certain amount of discharge after taking the pill, but it should not be mistaken for periods.
The pill should help to prevent
pregnancy by causing withdrawal bleeding within 3 weeks from the day of its intake.
If bleeding doesn't take place by 3 weeks, you need to take urine pregnancy test and seek medical attention promptly.
Hope the information provided would be helpful.
All the best.
