Hello and thank you for posting. 

I'm sorry you are worried about your scan results but I don't know how helpful we can be as we are not involved in your care.

I do not know exactly what they mean by borderline, but it could mean that they were not able to make a clear assessment that it was definitely a normal or abnormal picture.

This might mean you need further investigation to find out what is happening as these symptoms can happen for many reasons and most are not as serious as cancer. The NHS  has some information about irregular periods which you can see on their website here.

Unfortunately until they call and speak to you, no one is going to be able to say what might be going on. Although you have asked for other peoples outcomes with borderline scans they will have their own experiences and could cause you unnecessary anxiety.

Take care and I hope you get a phone call from the doctor soon.

Sarah.
