Hi I'm a 30 year old guy and I'm having sex with 25 year old girl her period is on the 17th if we had sex 4 days before she is due without condom and I came inside can she get pregnant ? And what if we had sex straight away after she finish her 3days period can she get pregnant and without condom too ?

Anytime you have sex you risk pregnancy, even using contraception.

Sex without protection increases the chances of pregnancy.

If you are not trying for a baby I strongly suggest to do not have sex or use a combined method of contraception,to lower the risk.

Wat we can use else then pills and condom ?

Yes, that would certainly cut down the risk, however no form of contraception is 100% effective.

Wat we can use else then pills and condom ?

Abstinence!!

If you have sex with her she can get pregnant even when using contraception/s.

Wat we can use else then pills and condom ?

Do you mean, 'What other forms of birth control can we use other than pills or condoms?'

Why do you not want to use condoms or 'pills'? What have you used with past girlfriends?

Yes, there are other methods and she should discuss them with her doctor to know which ones are best for her. Then, she can discuss them with you.
