Ttc after BC

Lauren
I stopped taking my birth control pills 3 weeks ago and I was suppose to get my period 3 days ago and still nothing. My husband and I had sex 5 days after i went off my BC pills, not sure if I was ovulating at the time. I've taken two test and both negative. Could it be to early to get a positive and maybe I am pregnant? Or is my period just having a hard time getting back to normal after stopping the pill. Hoping its that im pregnant!!
