Short-acting contraceptive pills work after seven days. Short-acting contraceptive pills are relatively low in hormones compared to long-acting contraceptive pills, and there is a medical requirement to take them from the first or fifth day of menstruation, and they need to be taken for seven consecutive days to have the effect of contraception. So if a woman has sex just 1-2 days after taking it, it is still necessary to use a condom at this time, otherwise the effect of contraception will not be achieved. If you take this pill, you must pay attention to the fact that you can’t stop after you take it, a cycle is 21 days, you need to take it continuously. If you stop taking the pill in the middle, you will have vaginal bleeding.
