Period ???? 8 months after chemo rad

I had a radical trachelectomy (Feb) followed by chemo radiation (finishing July)- today it feels like I am having a very light period. Is this possible ?
There is a tiny amount of blood and light almost cramping sensation .
Waiting for the consultant to call me back NOT very patiently

Anyone had anything similar ?

I hope you have had some reassurance 

Thanks . There has been no more blood . they are still wanting to see me which is good even though it scares me 

 

About the size of a 50p coin of blood on my pants in total
