hi, i am 16 female. my period was due on 21 july 2011. on the 19july i met with my partner, he ejaculated 4 times. the first three time he made sure there was no contact with my vagina at all. the sperm was on my hand and his left hand. we wiped this off with tissues and clothes. before he came the fourth time he rubbed his penis on the pelvic area (the skin above the vaginal area) for about 10 seconds, he then rubed it next to my left thigh for about 3 seconds when i told him to stop. about ten imns after this he ejaculated again, again making sure it was nowhere near my vagina or any vaginal areas. it was on his hands and mine but again we wiped. it is now the 25 and i have not had any sleep and have been worrying i might be pregnant as i have not had my period yet. i constanly am feeling sick but i dont know why, i haven yet been sick. what are the chances of me being pregnant?
