I sort of half had sex with my boyfriend about 4 times in the last 24 hours.. I say half because he didn't ejaculate, but it was unprotected, meaning I could be pregnant because there is sperm in precum?
Im asking my sister what I should do, should I wait and see if I'm pregnant or should I tell my mum straight away?
I don't want to stress her out without serious cause, if I told her and I was wrong, it would be bad for both of us because she is highly strung, and can be pretty frightening when she's scared. Please help me I'm 14 years old..

1st of all, wjat yhe hell are you doing having sex at 14! 2nd - yes yoi could have gotten pregnant but no trst could determine it yet. Go to drug store and check packages on home pregnancy tests on how long it might take before it can ne considered accurate. 3rd - USE CONDOMS

First: There is no sort of or half had sex. Lets call it what it is. It is full sex. Intercourse is intercourse.

Second: It does not matter whether he ejaculated or not. When it is unprotected there is always a risk to become pregnant.

Third: Now to answer your question. Stress that you put on yourself could effect your period. Just remember that. I would say wait and see if you get your regular period. Next time you decide to have sexual relations please please use a condom.

If you tell your mom NOW, then you and her can go down to the drug store and get what is called the "morning after pill" under various types and brands. It will help prevent pregnancy from happening.

Next as noted this is sex, there is no half or sort of sex, if he was inside for 1 or 2 seconds, that is sex.

So yes you could be pregnant from this, you would be a mother and he would be the father.

So many more issues that I could get into, but you are already scared and need to get help, So yes you need to talk to mom

As noted anytime you have penetration you risk pregnancy. If you are worried about getting pregnant then you should not be engaging in sexual intercourse. NO ONE (least of all a 14 yr old) should be engaging in sexual intercourse unless they are financially, emotionally and physically ready to have a child. You are neither.

You can try for a morning after pill if the timing is still right. But you need to start reviewing your behavior patterns for the future.
