Im 8 weeks 5 days pregnant according to my last period, but Im measuring 6 weeks and everything looks good...they just think I ovulated late, but I know that my husband was only home the month I concieved in the middle of my cycle, not at the end so I dont see how this is possible....I got a positive home pregnancy test just 1 day after I missed my period. How could I only be 6 weeks, but Ive already known that Im pregnant or 4? Could I just be measuring small and it could catch up in the next couple of weeks? Ive had 3 other babies and they all measured small, but not this small...thank you in advance for any help you can offer
