Everybody (and every pregnancy) is different, so yes! Consider yourself lucky. This may also be due to your diet, different diets during pregnancy may trigger symptoms such as morning sickness.
The two may not be connected. If you are spotting at 12 weeks I would see a doctor. If the spotting occured right after the vomiting, then I think the two are related, particularly if this is the first spotting that you have experienced. I need more information. however, with the limited info I have, I suspect that increased abdominal pressure caused a micro blood vessel (or two) to rupture. If it was a once off spotting that has not repeated itself or increased in intensity, then I suspect that was the cause. BUT, in the interests of aleviating the overprotective -- get it checked out by your gyno. Just remember that your pregnant body can take a great deal of stress and physical activity that can border on violent and still be running strong. Pregnant bodies are not as fragile as many think.
Vomiting
I think you mean "nausea." If you do, this is the term for feeling sick to the stomach, or nauseous. Basically, you feel like vomiting.
Dogs will be seen to eat long stranded grass when they feel nauseous. The grass somehow assists vomiting.
talk to your dr.
