Quoting nothing to see:" I ve never had morning sickness with my previous pregnancies. I understand each pregnancy is different, ... [snip!] ... be link. and I need your opinion. If you suffered morning sickness were you tired? do you think both things could be linked?"
I had terrible morning sickness with both of my kids! I am now finally feeling better at 17 weeks pregnant...I was very tired, nausea, and vomiting. It is normal with most people who are pregnant. Also, you have a 8 month old so you are going to be even more tired. Good luck! If you get too sick ask your doctor for some nausea med!
