Further to my previous post, whereby I havent had a period for 2 months now, I was due on 5th August but nothing again, I did a number of tests but all were negative, I am planning to do one again in the next day or so. I have started to get stomach cramps over the past day similar to those I get prior to when my period is about to start but each time nothing arrives. I am really confused as to what is going on - could they be a sign of pregnancy. I have noticed that I am generally more tired lately and also getting a bit of a lower back pain.
