Today i had sex with my girlfriend twice... and ...

she could be if you have sex before durring and after period yes there is a chance she is if she doesnt get her period than maybe she is but in some cases some women have their period and are pregnant. hope this helps

Lets see... if I remember correctly from 8th grade health class (long time ago)... based on a 28 day cycle starting from the day you start your period... ovulation occurs around the second and third week for three days... so from the 14-24 day area... and sperm can stay active fro up to 48 hrs.. so if your gf has a regular cycle... your chances are very high she could in fact be preg... she can also buy an ovulation test in a drug store to see if she is actually ovulating when you guys try...good luck

 I have two children, both a surprise ! At the time i was not ovulating and was days before expected period in fact one preg i still had a very slight period .P.S the first time we only just begun to have sex and i wasent ready and guess what? 9 mos later baby boy! See u really just never know i would never go by any rule it just happens by flook sometimes.

I hope this was helpfull good luck and im sure when u get home and get married (just a thought no pressure:) u will have plenty of catching up to do
