Worried

Ok. We've been ttc since July '14. I know it's not been that long. Well glow just said that my fertile widow is now. We've been following the rules about coupling often during this time. But this past week I've felt odd. Very small faint cramps, nausea, and decreased appetite (which that is nothing like me I love food). I took a HPT and it said negative. I'm not sick other wise I'd have fever and other symptoms and I don't and is not food poisoning cause that doesn't last a whole week. Just trying to figure out what's going on. Anxious. And worried that I'm getting false negatives.
