It is important to say that pregnancy is possible whenever sperm comes into contact with the vagina. Although pre-ejaculate doesn’t itself contain sperm, it can pick up left over sperm in the urethra when it leaves the body, creating a risk for pregnancy. You are definitely right that sperm can live in the vagina for 5 days, but in terms of your question about the vagina killing the sperm in the pre-ejaculate, there is really no way to know. It is just important to know if there is sperm present, and it made contact with the vagina, there is a risk of pregnancy.
Once you’ve started taking a hormonal method of birth control, you will have to abstain or use a back-up method (like condoms) for one week until it will be effective in preventing pregnancy. It takes one week for the hormones to “kick in” and be effective in preventing pregnancy.
But keep in mind that your birth control is only going to be effective if you’re taking it correctly. Depending on which method you are using, there are special instructions on how to use it so that it’s most effective.
- If you’re on the pill, you need to remember to take it at the same time every day.
- If you’re on the patch, you need to remember to put a new one on once a week for three weeks.
- If you’re on the ring, you need to remember to put a new one in once every three weeks.
- If you’re on the shot, you need to remember to get the shot once every three months.
- If you’re on the Nexplanon, you need to remember to get it changed out every three years.
- If you’re on the IUD you need to remember to get it changed out every 3-5 years.
If you are taking your hormonal method correctly and consistently, you will be up to 99% protected from pregnancy. If you are not taking it correctly however, effectiveness will go down.
In conclusion, if your boyfriend ejaculates inside of you but you’re taking your birth control correctly, you will be up to 99% protected from pregnancy. It’s always a good idea to use some type of barrier method (like condoms) in addition to a hormonal method of birth control to help reduce the risk of STI transmission.
