I agree with Chody47, ask to have bloods taken!
Even after I had 3 positive HPT's, 2 blood tests I still didn't believe it! lol... I had to ask for an ultrasound to make it real for me!
I didn't vomit either, just fet sick and very tired!! I would say you are pregnant darling!! If in doubt, don't fee silly asking for bloods or whatever you need to confirm it!!!
