Moms!!!!! Please answer

So I am pregnant with baby number 2!!! This pregnancy is very very different, just different feelings. One I have notice is perfum smells don't bother me. With my daughter I would gag and run to the bathroom I just couldn't stand to be around it. This time around I'm in my second month and I don't mind it. Has anyone ever had completely different pregnancies and had the same sex? Or does that usually mean you're having the opposite sex. I know it sounds silly I'm just curious to what others have experienced.
