Me and my partner decided to officially try for a baby this month (although we haven't been using contraception for a while now). I have had lower back ache, cramping, very tender breasts and have been very emotional for the past couple of weeks. We have been nervously waiting for me to come on for a week or so, I did a couple of negative hpt's before I was due on. I was supposed to come on yesterday but still no sign. I did have a spell of irregular periods a few months ago, they were always early periods though, never late. They seemed to have regulated again in the past few months. However, I did a hpt today and it was negative. Is there any chance I could still be pregnant?? Or is my late period likely to be caused by other factors?? If anyone has had a similar experience, please let me know xxx
