How long did it take you to get a BFP after stopping the pill?

Hi Ladies, so me and my partner have decided to try for our second child! (first DD is 3 and 1/2 years old) 
I stopped the pill mid pack at the end of may and had a withdrawal bleed at the start of June, but I haven't had anything since. Is this normal or is there a chance I could be pregnant already? 
Thank you for any responses! xxx
