There is no in vivo fertilization after the same sex. I'm afraid that in case I take levonorgestrel tablets and continue the same sex within 4 hours, there is no in vivo fertilization. Is this medicine useful?
According to the situation described by you, I think the probability of pregnancy is small. I don't need to consider pregnancy. Just pay attention to rest and wait patiently for menstruation. It is recommended that you try to take other effective contraceptive methods and use emergency contraceptives as little as possible. The side effects of emergency contraceptives are relatively large.
After eating the emergency contraceptive pill, you can have the same room. Generally, it doesn't have much impact in this case. The emergency contraceptive pill needs to be taken within 72 hours after sex. The earlier the time, the better the contraceptive effect will be. However, it must be noted that the contraceptive pill can only be taken once a month and no more than three times a year.
There is no fertilization in the body when having a roommate, which generally won't be pregnant, but you have a roommate after taking contraceptives. If ejaculation occurs in the body after having a roommate, contraceptives have no effect. It only has the effect of avoiding pregnancy for the ejaculation before taking drugs. If there is no internal ejaculation, the possibility of pregnancy is generally small.
