8 weeks pregnant with twins, confirmed, but no morning sickness or other symptoms just tired+bloated+restless legs should i be worried? is this normal

Yes, and congrats!: I also have twins, now age 22! That's the best thing in the World. I had no morning sickness till much later in the pregnancy. I did get very tired in the first trimester, ( also with my next baby, single pregnancy). I remember getting the morning sickness more closely to 10-12 weeks gestation and maybe even later. Some women don't even get morning sickness. It's different for each women. enjoy!
