It is completely normal to have alternating hunger and icky feelings. Morning sickness can last for some women there entire pregnancy. No 2 pregnancies are going to be the same. Ever. This is a different pregnancy, so you will feel differently. You are older now and your body has already experienced pregnancy.

These feelings do not indicate twins. Being large for dates could indicate a multiple pregnancy - but you would need an ultrasound to be sure.

Welcome to my world, honey.
Hahah, i'm almost 12wks,
&.I go from feeling disgusting,
nauseous, just flat out ew..
&then 3 minutes later .I'm like ".I am starving."

Thanks, that makes me feel better, my "babys daddy" lol, has been teasing me about having twins now for like a weeks cause they are in his fam., even if I did have twins it wouldnt be so bad (gods will I guess) but I think for now ill stick to not thinking about it!!

twins are not passed down through the father's line. They are from the mother's genetics (unless identical. But idents are a fluke of nature. Not genetically based.). The genes to produce 2 eggs comes from your side. Your boyfriend wouldn't have anything to do with it. ;)
