Since the first moment I got a positive pregnancy test y dowloaded this app at it showed me my due date and all the information that was like a month and a half ago... last week before I got my appoiment at the dr this app said I was 10w some days... But at the doctors it measured 8w and some days, she gave me the same due date so I'm really confused how far I am... this app it showing me I'm 11w now... and I guess Its measuring 9 weeks? :/ .
