It can be cause you are worrying about it. And no you are not pregnant, sperm have to be in your vagina to get you pregnant.
time will tell. missing your period in less then a day, with no intercourse then it's probably your mind messing with you.
Relax! Breathe and inhale.
It is really very unlikely that you are. Not only do you have to be ovulating to get pregnant, but there definitely needs to be ejaculation inside you. I wouldn't worry. Your period being late may have something to do with you being stressed about possible pregnancy.
i am worried.. i cant stop thinking about it. there is no way for me to be pregnant at all right?
No. without intercourse, you can not be pregnant.
so if i stop worrying, do you think there is a better chance the i will start
im sure this is driving you crazy but i am just worried. there is no way that sperm could have went into me even though he had his boxers on?
No. You're not pregnant. :-)
If you're that worried, take a pregnancy test. It should be accurate now if your period is due. It will be negative, and you can breathe a sigh of relief! Your period is more likely to arrive on time when you are not so stressed out.
Not to sound preachy, but you can avoid some of this worry in the future by practicing safe sex. Try birth control pills, or have him wear a condom anytime you will be fooling around, whether you intend to have intercourse or not.
