Could it be? Advice/help needed x

Ashley
Hey ladies 
Need some advise
I am currently 7dpo af due in 9 days and been experiencing what feels like period pains. They not awful but like a dull ache and occasionally I feel a little flutter.
Anyone else experienced this?
I have pcos and been trying for last year. Just been put on clomid although not started taking yet as appointing was right in middle of fertile window and didn't wanna jeopardise starting my af inducing drugs incase I conceived. Wishful thinking! 
My periods are always irregular but just got an odd feeling.
Hope someone can help x
