Last month (June) I had my period on the 5th, (my periods generally last 3 days) and then the 14th of June I again had my period. My boyfriend and I do not have unprotected sex seeing as just 4 months ago we just had a baby and we want to wait till he is a bit older to have another one. However this month (July) I have yet to start my period. If I go from the 5th I should have started on July 3rd and if I go by the 14th I should start tomorrow. However; I have no symptoms of starting. Around the 3rd I had the PMS crankiness and the cramping, and the a few days ago I had the same thing. I'm not nervous that I might be pregnant because I was having kidney problems and I had to have surgery due to that (June 23rd) and my boyfriend and I have only had sex 2 times in the last 3 months. Once was just the night before last and once was just a few weeks ago. However; once again protection was used. What could this be? Please help!!!
