Comparing pregnancies?!?!?!

So for the mommies who have had more than one child, can you compare your pregnancies??? If you have had 2 girls was the experience the same. Also vice versa 2 boys or 1 of each. My friends tell me I can't have 2 good pregnancies. I won't find out the gender until October, but with this being so different than my boy, I'm convinced this baby will be a girl.
