LATE AF! Help! PLEASE!

MK
My husband and I are TTC and I recently went off birth control in late Dec. My last cycle was in Dec. I've taken several hpt's- all negative. I am going crazy! I am moody, hungry, tired, bloated, have sore breasts- the works! I am planning to call my Obgyn at the end of the month of AF still doesn't arrive. How long did it take you to start your period after stopping birth control? Any advice or encouragement? I am really in need of some support right now!
