it still leaves at least a 2 to 3% chance... u may wait...and i believe if u can get a condom a birth control pill won't be a prob either..
okay, can you tell me though how to obtain birth control at the age of 17, while living in Massachusetts? and if you had to, to ease my worrying, tell me the chance(in precent) that she is going to become pregnant, based on what i told you? i ask this with the intent of still taking it seriously, but hopefully without the worry.
The average women will release their egg about 14 days from the first day of their period. Give or take a few days since everyone is different. It defiantly is a possibility because of the condom breaking. Cutegirl20 is right. If you are worried you should get the emergency contraceptive pill. I assume you guys are young and probably not ready for a child. The change that she is, is slight, but however there is still a chance. Also I would recommend looking into another form of birth control for the future in combination with condoms, she may want to take the pill, patch, ring, or you may use a foam or gel that will kill the sperm. It is always better to have 2 different types of contraceptives. In case on fails. Good luck!
well.. any fertile couple has 25% chances of conceiving if they have unprotected sex or any contraceptive failure.. being the first time doesn't affect the chances of getting pregnant.. u r sure that u didn't ejaculate so that reduces the chances a bit but i will not say completely to no chances.. u just can't predict it like that.. so just wait for her next periods to come.. if u are still scared i would not have suggested but since it was a case of contraceptive failure u can go for an emergency contraceptive pill if it's not been 72 hrs since the time u had sex.. it will change her cycle a bit and might cause some more physical chances like nausea and headache.. but if it's been more than 72 hrs it will not be able to help in any ways.. ask ur girlfriend to calculate the days and see if it was her fertile day.. a little more specifications about your doubt can help in calculating the chances of getting pregnant.. good luck..
