If you vomit after taking the pill, it depends on the length of time you have been taking it. If you vomit up the pill right after taking it, you need to take a refill in time to prevent the possibility of contraceptive failure. If you take the pill for more than half an hour, you don’t need to take it, but you need to pay attention to other contraceptive methods to prevent the possibility of unwanted pregnancy. Common oral contraceptives include the combination long-acting oral contraceptive pill and the combination short-acting oral contraceptive pill, the family visitation pill and the emergency contraceptive pill. Most of them can be relieved by themselves, but if there are serious reactions, it is necessary to stop taking the pill or change it.
