Soooo I'm still BFing DS (14 months) and haven't had a period since ooooh October 2008!! But for the past week I've had weird waves of nausea, no actual sickness, just slightly churning tum, a queasy feeling and too much saliva in the mouth, plus the need to burp every now and then. Classy. Very much like the morning sickness I had with DS. Now I've done a pregnancy test and it's negative and by the time I got nausea with DS had had oodles of positive tests by then. I will test again if it continues. But assuming I'm not pregnant what could it be? Does anyone know of anything else that can cause mild(ish) nausea for this long? Please help am finding myself utterly preoccupied by this and was sure when I tested this morning I'd find a BFP. Anyone??
