You shouldn't be using withdrawal in the first place, because it's NOT Birth Control - and yes, you could be pregnant!
The pullout method is the most unreliable method of birth control. Pregnancy is always a possibility - be protected.
Yes! It happens all the time!
Yes!
No this is not true. The likelihood of you becomming pregnant depends on where you are in your cycle and how fertile you are. The withdrawal method has a very high faiure rate. You should use a condom and not use the pullout/withdrawal method.
Nothing!
Technically no, but since sperm are microscopic you can't always know if any has. You can become pregnant without the man ejaculating though -- the precum (when the penis sort of "leaks" a little bit with arousal or as he approaches orgasm) contains sperm, and this is more than enough to get you pregnant. This is why the "pullout" method of contraception is so ineffective.
Yes, you could be pregnant, because withdrawal DOESN'T protect you against pregnancy!
First I will always say that unless you are abstinent, there is always a possibility of being pregnant. Yes, you can get pregnant. Common myths suggest that you cannot get pregnant while on your period, that is false information as well; although it is less likely it is still possible. You can also get pregnant from pre-ejaculate as you might not have thought because pre-ejaculate still contains sperm/semen. The pullout or withdraw method can still have sperm or semen that can come in contact with the vagina and get a female pregnant.
It is quite possible. It is possible you could get pregnant even with the "pullout" method. This is because the male releases sperm in his pre-ejaculate as well. Though there are smaller amounts, it is still enough to get a female pregnant. Try using condoms or other form of contraception for pregnancy prevention.
EXTREMELY dangerous, so don't even THINK about using it!
It can be used to prevent pregnancy when no other method is available. There are no medical or hormonal side effects. No prescription is necessary. It is free.
YES If a guy has his penis in or around your vagina and it is erect, there is a pretty good chance there is some sperm coming out, whether this is when he comes or before, which is called "pre-come". If a guy has his penis close or in your vagina, even though you are wearing some underwear, there is a chance you can get pregnant.
