I am a 16 year old, and had sex the other nyt. I wanted to but now I am nervous. We used a condomn and we didn't do it for long, my boyfriend didn't even ejaculate. My period was supposed to be round this time, but its not. Do you think I could be pregnant or do you think my mind is delaying my period? What are the chances.

And also if I was pregnant when would you start feeling syptoms such as putting on weight or breasts growing??

Please answer instead of just looking... please:( :confused:

Calm down. Right I doubt you are pregnant because if it was the other night it would have been at a less fertile time in you period and you used a condom (98%[1] if used properly), the law of probability would mean you would have to times them together - further reducing the chance.

The fact you boyfriend didn't ejaculate kind of reduces it as well - although you can get pregnant form pre ejaculate - as it can contain sperms

Ah hah - just found a site that's done the sums I was going to do

Right you have to relax, the odds are you are not pregnant. However for piece of mind and added security you should investigate other, more effective methods of contraception (ie the pill) and combine condoms with it. Of course the only guarantee is abstinence.
