probably tmi

So my husband told me that my nipples look darker and bigger. He told me I should take a pregnancy test because he has a feeling. But I don't know if I should because I'll feel really bad if I let him down and I really want it to be true. But here's the scoop. I only just had my period less than a week ago and it's probably not possible that I ovulated that early. I've asked him before if they look darker and he's always said no but this time he said yes and I'm not so sure I believe him. But I just don't know if I should take a test or not it's only been a week. It seems too soon....
