Been on hrt over a year sequential patches and utro, in January I had spotting for 9 days mid cycle onwards, February was ok, then this month had a day mid cycle, then a week later more spotting for 5 days

No idea what's going on, Dr said after first lot if keeps happening will need a scan, now I have to wait until the 31st for a call back. Am worried it might be something sinister.
