cycle buddies?!

Hi all,
I'm very new to all this. I'm 24 from London and looking to conceive baby no 1. 
I'm due on the 3rd of November now, previous was September 26th so cycle is around 38 days. Although still trying to figure that out after coming of contraceptive pill gederal. 
Has anyone else come off this pill? How were your periods affected?
If your due around the same time let me know... this cycle buddies thing sounds great!
