Doctor confirmed my pregnancy!!!!!

Went to the doctor and she said yes I'm pregnant with my second baby! But I don't remember having them take ten tubes of my blood. But at least I know I'm not crazy and there is alittle bean in there !!my first soon is in two weeks !! So excited and can't wait ,I just wish my husband was here to experience this with me ,he's in the military and at school for some training and won't be back till September! The prenatal sample she gave me have higher number of vitamin than the one I'm taking should I take the one she gave me ???
