Late period- negative test :(

So my last cycle was May 30 through June 3rd. My husband and I decided that would be my last package of birth control and stopped it on Friday the third. with my birth control I knew my exact days that I would start. I was very consistent however now that I'm off my birth control I am two days late. Lately all I have been thinking about is expanding our family and adding a little one I can't get it off my mind however I took a pregnancy test today and it came back negative I am a little sad because Father's Day we found out my sister-in-law is pregnant all though very happy for her I wish it was me. Has anyone else had the symptoms also ladies how long did it take you to conceive after getting off your birth control?
*** took another test right away this morning BFN
** now 4-5 days late and no more signs of AF?
