Irregular bleeding 5 months off the evra patch!? HELP!?

Hi ladies I came off the evra patch end of July (had af/break through 1st august) so I'm currently on month 5 ttc .....

First few months I was getting spotting every now and again but no true af

This month had my first true af that lasted 8 days heavily but a day after it stopped I started spotting and still am I'm on cd17

I'm booked in to see a DR but wondered if anyone had the same problem

Please can anyone help? 

Thank you
