I normally have irregular periods, but nothing like this. for the past 5 days I have been spotting brown. there's been no red and my period is late. normally with my period my breasts are extremely sore a week prior and I have horrible cramps. with this I'm not cramping at all. I'm just feeling some discomfort in my abdomen. i've had horrible headaches and have felt sick to my stomach for the past couple days. i've also been extremely tired and have had horrible mood swings. I had a bhcg test done yesterday and it came back negative. I really do feel pregnant. is this just wishful thinking?
