I have a 28 day cycle to the hour but am over 2 weeks late. I have taken several pregnancy tests but they all show negative. I am not stressed haven't been sick or started exercising any more then normal. I have an occasional about of nausea. I went to the doctor but she wasn't very helpful and told me it was too early to know anything yet. I have been off the pill for over 6 months. Can anyone help?
