confused....

Samantha

So I am a diabetic with 2 previous babies. I am three days late for AF and have every symptom I previously had while pregnant including a massive drop in my average blood sugars, nausea, bloating, dizzyness, sore boobs and back! I got 2 vvfp on wondfos but all neg on frer tests. still no bfp on frer but no change in symptoms. how do I interpret this?
