am i with child or just crazy??????

my first time was on February the 6th , my second was February the 20th and my last was march the 6th with the same male. from the 6th, 2 weeks later i threw up some white, clear stuff. i paid it no attention. i was beginning to have back pains and leg pains and stomach pain and pee alot. i contacted the male and told him i might be pregnant he denied it.... he said we used a condom the second time he couldn't find it and the third time idk where the condom was. my period useless lasts for 6 days, now there 3 days or less. i use to be very active, but now i'm just tired and to lazy to do anything. did i tell you that my conceiving days are the 6th.
