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 I'm always tired. Im always hungry. Im peeing a lot more than usual. If I am pregnant, according to online web calculations, I conceived on the 11th of October, which is when I had sex, but its so early could I really be pregnant?
