Hello and welcome to HCM
Conception and hence pregnancy
depends on the period of the cycle.
Conception takes place when within two days of ovulation. If the sperm meets the released ovum within two days then only pregnancy takes place.
is an emergency contraceptive
which should be taken (4 pills) within 120 hours of having unprotected sex and followed by 4 tablets 12 hours later.
You will get your periods according to your cycle.
Thanks and take care.
