I am 15 days late for my period, I have 5 negative tests. Could I still be pregnant? If not im wondering if there is some other health issue going on. I have been very tired, dizzy at times, cramping, bloated, acne, and my stools the past two days have been very light colored, and also I have been going about 2 times a day which isn t normal for me. I would think maybe im pregnant but im just not sure.
