How long after stopping birth control did it take to concieve?

My husband and I have been TTC for 2 months and so far nothing. I went off birth control the end of April and and we have been trying since May. I wasn't trying with my first one and with our second one it only took us a month. I have Ben doing the ovulation tests as we'll.   I am healthy and so is my husband. Just a little down about it all.
