So hw can I know that I will become pregnant or in how much tym I'll be pregnant or what are the symptoms of pregnancy & hw can I prevent from pregnancy *** help me

I'm sorry, I don't understand your question.

Would you mind re-typing it for me in complete words, not text talk. Thank you.

You wonder if you will get pregnant from anal sex..? No.

How can you prevent pregnancy? Are you serious? There is only ONE way to prevent pregnancy... don't have sex. EVERYTHING else has the possibility of pregnancy.

This isn't really a serious question, is it?

I guess the class on sex education was missed. Oh well!

I believe that this is an honest question, even the part about anal sex. She simply wants to know all about what it takes to get pregnant, how long, and what the signs are.

You get pregnant by sperm reaching an egg that comes down into your uterus. The sperm can swim up your vagina, through the cervix, into the uterus, (and even into the fallopian tube, rarely). Even though a sperm fertilizes an egg usually in the middle of your period, we say you can get pregnant ANY TIME a penis gets near a vagina and even drips one drop of sperm - because it does happen.
The way you know if you are pregnant really needs a test kit which you can buy in a drugstore, in most of the world anyway. Missing a period or feeling naseous or tender breasts are signs, there are many signs, but they don't prove anything. You can also have a light period and be pregnant, so again, you need that urine test. You can't test for a few weeks after you think you might be pregnant.

You can not actually get pregnant from the act of anal sex but if I was unprotected sex or as you said the condom leaked if any ran down it could very much possibly fertalize a egg in which case you can become pregnant since you said you had sex on the 21st if you are worried you still have the option to take the morning after pill I know plan-B can be taken within 72 hours after unprotected sex. Good luck
