You can’t get pregnant if you wear a condom during an easy pregnancy, but first make sure that the condom didn’t break or fall off halfway through sex. If the condom does not break or fall off after sex, you will not get pregnant. However, if there is a hole in the condom, it may cause pregnancy. If you don’t want to have children, you can take the emergency contraceptive pill, which works within 72 hours of having sex, and the earlier you take it, the more effective it will be. The sooner you take it, the more effective it will be. If you take it after 72 hours, it won’t work, and if the condom falls off in the vagina in the middle of the day, it’s ineffective, and you need to take the emergency contraceptive pill to prevent pregnancy.
