2Days?

It's down to 2 day until AF is sopose to arrive I'm hoping she doesn't arrive for the next nine months. I'm really nervous about testing. I haven't had any signs of anything until today. I've has some cramps I've been dizzy and moody and irritable all day and I'm afraid that its AF? why is it so easy for people that don't want a baby to get pregnant but it takes months even years for those of us that want a baby...I just don't understand??
