Should I be concerned?

Ok so I stopped taking my birth control pills the 22nd of December, had withdrawal bleeding 25-29th. I did this for myself , since I read that there was a higher spike of breast cancer with the pill. My period (or so Glow says) isn’t for 11 more days but it’s going by that withdrawal period I had. My last real period ended the 11th of last month. Course I heard it could take a while for my period to come back. I just don’t wanna alarm my husband . I’m not really having early pregnancy signs. But nausea and headaches but this is from getting off Cymbalta, back in November. Should I be alarmed? Or am I okay ?
