2 Totally Different Pregnancies (so far).. different gender or just coincidence?

Kristin • Married 8/16/14💍 Pierce Jaxon: 6/5/16💙👶🏼 Logan Marie: 2/27/18 🎀👶🏼.
I am still really early but I am already having a completely different pregnancy than my last (a year ago). 
With my son I knew I was pregnant before my BFP, my boobs killed me and I felt like a million bucks (for the first couple weeks-nausea started at 7 weeks). I had some slight acne and was never tired! 
This pregnancy I was convinced I wasn't pregnant, my boobs still don't hurt and I am an emotional mess. I cry and get sooo angry so quickly I think I am going insane. There's a lot more cramping and stretching feelings and I get waves of nausea already. I am sooo tired and sleep like a rock! 
So for those of you woman that had one gender of each... what were your differences? Obviously I don't know if I am having a boy or girl but it just feels so different! Anyways happy pregnancy to you all!
