Sounds like your pregnant to me too!

I guess we all deep inside doubt ourselves just to prepare to be told the worst. I was like that, while i saw a blob at my 6 week scan i didnt believe it was a baby until my 12 week scan when i saw my baby.

My boobs changed further along, i did get darker veins but they didnt darken in colour until about 20 odd weeks.

As for feeling sick, i had awful awful morning sickness but some women dont experience much or even at all.

And as for the blood test some doctors are convinced women are pregnant by the home tests. Because you had more than one positive thats enough confirmation for them. I only got a blood test because it was really early days.

HTH
