Birth Control, late periods & TTC

​I just recently went off my birth control to start TTC! My husband and I have been talking for awhile about getting pregnant and last month decided that after this cycle of birth control that we'd try! On my birth control I usually have a normal period and it comes like clockwork. This month, while on birth control, my period never came. And now that I'm completely off birth control I still haven't had a period! Should I test or wait longer since I have just gotten off my birth control?
