I am trying to get pregnant. Im 19, and athletic. I ve calculated my last two periods. I had one from September 1st- September 4th. And then again September 27th to October 3rd. My average cycle is 26 days, and my average Lutheal phase is 11 days. I ve been having unprotected with my boyfriend all week. I feel pregnant, my breasts are itchy, I m having trouble falling asleep, but im always tired. Im always hungry. Im peeing a lot more than usual. If I am pregnant, according to online web calculations, I concieved on the 11th of october, which is when I had sex, but its so early could I really be prego?
