Hi me and my gf we had sex on 18th July 2009.. everything was going well and she gave me a blow job and i ejaculated... she sucked up most of the sperm and after that i even wiped my penis on my bedsheets...we proceeded to have sex but i put the condom on backwards it wouldn't roll down it went a quarter way and i rolled it back up and put it on the correct way, I never ejaculated in her even with a condom

She says shes been having headaches and feeling tired and i know those are symptoms of pregnancy. What are her chances of being pregnant? We are both underage and we cant afford to have a baby our parents are very strict and they cant find out... shes stressing out and she cant sleep or concentrate on anything

P.S her period is also very irregular

Thank You very much.
