BFN...?

So I let my wonderful husband talk me into taking a test. He is just as excited as I am. And since I have sore breast and my stomachs upset I thought what the heck I'll just retest in another couple of days. I got a BFN...I knew it would be to early since I'm only 7 dpo. But now I can't help but feel discouraged. ? My brain hasn't shut off the symptoms so I don't think it's in my head. But man I should have listened to myself and waited because I still feel crappy even though I knew it was to early. Now I feel like the retest is going to be the same. ?
