I'm so scared to take a test n it not be what I want. Doctor appointment on the 2nd. I'm so scared cause I been pray for a baby, now I think its finally here. I keep telling myself my period coming but no signs of it... I really feel like crying right now cause I feel this is it but I'm so scared.. Any advice or someone going thru the same thing???? Or did somebody go thru this n the past n find out they was pregnant???
