purebred husky preg need answers..? help?

now i no i will probably be abused by some for this but this was an accident.. my 9 month old pure bred husky was onheat and our neighbours across the road have a pure bred husky and they have play dates except not when on heat but he had jumped the fence one night and made it into our yar and we woke to her screaming as we found them tied together.. i spoke to the vet as i was worried for her health as nothing means more to me and they told me if she can be on heat than she will be fine being preg and wont jeopardise her health and if they were tied than shes most definately preg.. she has a vet appoinment in a few weeks..
and dont tel me to spay her its too late now and i wil consider it and be more cautous in the future.

she has been throwing up abit lately (i take it thats apart of being preg like morning sickness)
is there anything to help ease her pain?

and how many do huskies have in a litter generally??
in their first litter? and will it affect her from being not completely developed?

and will colours vary or only be the same as the mother and father?

thankyou give asmuch imput as possible please
