I took three home preg tests and found them all to be positive.. when I went to the doc I took a test there and it turned out to be negative. My doc said that thier is such thing as a chemical pregnancy and that I had to go back in 2 weeks if I still had'nt gotten my period. I'm so worried now that it's gonna come that i keep checking any little cramp I freak out about. My husband and I are so excited to have a baby but I'm so scared that it's gonna turn out to be nothing. How am I supposed to know if this is really real? Just needed to vent.. thanks
