I am 8 days late for my period, and my usual cycle is 28-32 days. However, today is the 38th day and there has been nothing. I have taken 2 pregnancy tests, one on Friday and today. Both have come negative. However, I am experiencing symptoms such as dizzinnes, faintness, and my pelvic region/stomach area is sometimes not in pain, but I feel cramps. I am confused..?
