Got back from doc's today ref my pains and strange periods. He said it is nothing to worry about, could be because of my age or coming of pill even though I was only on it for 3 months. Will keep an eye on it. Cycle only seems to be 3 weeks long now but I have period pains and feelings already and I only finished last week!
He has referred me to someone to talk about my health anxiety though so that is good, not sure how long I will have to wait but welcome any help.
