BFN wish my periods would sort themselves out!!

Shirley
BFN this morning from first pee! 
Only had about 6 very light days of AF since coming off the pill in May.
And this month was the worst it was 5 days early then expect and only brownish coloured stuff which was only there when I wiped for one and a half days ( i was sure it was IP ) 
I wish my periods would regulate we are so TTC
Has this happened to anyone else?
How long did it take your periods to get back to normal after coming off the pill?
