Neg / faint lines ☹️💔

I'm super late ! I've never been nearly a week late maybe 2/3 days but not that long ! Me and my hubby have had sex on my most fertile days all week long and then one day a week this whole month! Even in my missed period days . And I've been getting negatives and faint lines .. I've don't a digital and not pregnant I have a strong feeling I am pregnant I've been getting super nausea almost everyday . I've been having KILLER headache which I hardly ever get headaches sore side boobs very tired so days . I've been have clear/raw egg whites every single day some small amounts other a really good amount . I just don't know what else to do anymore, I've googled that some women don't get their BPN until 2 weeks after their missed period. So I'm just confused 😔no I'm not stressing.
