Hello,
As you had taken the pill within 4 hours of intercourse, there is almost no chance of you getting pregnant.
Let me mention few facts about after pill:
1) When taken in
2) If within 24 hrs, it is 95% effective. So, you are on a very safer side
Regarding birth control pills, they can’t prevent
pregnancy on instant basis but they need to be used consistently as prescribed. Moreover, they are not recommended for emergency or post coital
contraception.
If you are going to have intercourse frequently, I would suggest you to go for
oral contraceptive pills. But, as far as this coital act is concerned, after pill is enough to prevent pregnancy.
Still if you are doubtful, kindly go for urine pregnancy test after 3 weeks with a kit at home by yourself.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Pallavi.m
