I've had terrible nausea most of the day for the last three weeks (I'm 6w3d), overwhelming hunger, lots of cramps and occasional heartburn. It was, in an odd way, reassuring. Tonight it seems like all my symptoms have vanished and there is nothing. I have had cramps most of the day (no spotting) and am wondering what I should do. Our first scan isn't until Tuesday, but with the lack of symptoms this afternoon and tonight, I'm wondering if somehow, I have lost the baby. Is it normal for symptoms to just vanish so early?
