Hi, next choice
, a Progerterone. It has a high success rate. It is called as morning after pill or emergency contraceptive pill
. The increase in the level of progesterone
on taking levonorgesterol, & the sudden fall in its level on stopping it results in withdrawal bleeding & this is the basis of its action. You need not worry as the chances of conception are minimal because the luteolytic action of the drug Levonorgestrel will prevent the conception.
Temporary disruption of menstrual cycle is commonly reported after taking Levonorgestrel. If taken before ovulation it results in immediate withdrawal bleeding ie., within 7 days of taking the pill. But if taken during the late luteal phase, it delays the menstruation
by few days. Since you have taken during the late luteal phase, there may be a delay.
