Help haven't had a period

Claire
Hi ladies I'm 24 on Friday, I stopped taking my pill last month, my period finished on 10/12/15 and haven't had one since. I think I've been on the pill for about 7 years. I would normally come on around now when on the pill not sure how long to wait before testing? 
I seem to be going to the toilet a lot but have no other symptoms.. But also have stomach cramps?
