I've been feeling really nauseous, dizzy and have had slight headaches off and on every day now for about 2 weeks. I don't really have any breast tenderness that I've noticed but I have felt crampy here and there. Generally I just feel weird, but (back before I was pregnant) I never felt nauseous when I was about to get my period, and that's my main symptom. Sometimes I really feel like puking and need to lay my head down.
Throughout my BFing experience, I would feel really nauseous if I didn't eat enough, but now even after I eat I feel sick. I'm pumping at work 2-4x a day now and when I'm home my DS nurses every 2 hours on average (and nurses 2-4 times a night). I took a PG test last week to see what was going on, and it was negative. I haven't had a postpartum period yet, so DH and I have not been super careful because of that.
Does the return of AF feel like this, and if so, how long could this go on for before it comes?
