Late period

Cynthia • 20, engaged and ttc.
Okay so, I was on depo for a really long time. Stopped taking it and it took me like 7 months to finally have a period. Since I first had a period though they have been totally normal . 28 days exactly and regular flow (3 periods since then) I also experienced extreme cramps each time. Today my period was due. No cramps and no sign of af whatsoever. Besides tired, and sore breasts. Haven't even had any appetite at all. Been trying to concieve. Scared to take a test . Should I wait a few days or what ?
