thanks for your query.
If you had vaginal penetration, it is technically possible to get pregnant.
35 is an oral contraceptive
pill, not ideally recommended for emergency contraception
, and if at all , it is to be taken in a higher dose than usual.
Please consult your healthcare provider for the exact dose of the emergency contraception, though it should ideally be taken within 24 hours.
Take care, and use protection for the rest of your cycle.
