The same way you do. Condoms & birth control.
Don't have sex.
no maryjane will not stop a pregnancy or harm a pregnacy but you shouldnt do it
No
It may help "prevent" pregnancy, but no pill is 100% guaranteed to keep someone from getting pregnant. The only proven methods are * totally abstaining from sexual activities * having a hysterectomy operation
To keep you from getting pregnant
No.
You can't, unless you make the bull a steer.
The only 100% sure way of not conceiving is not to have sex or to have a hysterectomy - even getting your tubes tied is not 100%.If you are using condoms every time you have sex and taking your BCP everyday as directed - you are doing everything humanly possible not to get pregnant. Using a condom with spermicide offers even more protection when used a directed to help reduce the risk of pregnancy in case a condom tears or comes off in the vagina. So keep on doing what you are doing - the odds are in your favor, that you will not get pregnant until you decide you want to have a baby.
No, there is no food or beverage that prevents pregnancy.
If you switch between anal and vaginal intercourse without changing condoms than that could do it. Or you have gonorrhea.
Answer Having no sex at all.Without condoms or birth control you can't prevent pregnancy if you keep on having sex.First of all, without condoms you can spread all kinds of diseases if you or your partner carries HIV or any other STD's.Second, birth control is just the extra protection against pregnancy along with condoms, don't think you can just use birth control and go on without condoms. Unless you know for sure you or your partner don't carry HIV or any STD's and also don't mind about getting pregnant. Or you can have a surgery which does not go without risks and is non-reversible.
