Wondering about twin pregnancy?

I have read through and a lot of people have answered signs and symptoms of twin pregnancy- most important being a sonogram that shows 2 babies. This is my 6th pregnancy!! Yes number 6!!! I can hardly believe that number. I have 3 boys and had 2 miscarriages, had blood done on friday and on monday I go in for my first scan with this pregnancy. I am very tired- like extremely this time around. It is hard for me to stay awake and I need a nap almost every afternoon- that and a feeling like maybe this is twins is really making this upcoming sono exciting! Anyone who has had twins ((or higher)) how did u feel in very early stages of pregnancy? **by the way on monday if I can add a post to this one I'll let everyone in yahoo land know if I was right!))
