Period delayed

Few weeks ago I had a bad “break up” argument with husband 😰 cried my guts out for a whole day non stop and he really break my heart 💔 and caused so much pain. Now I’m strong and doing ok but now I’m late for my period, so far a week late and no period yet just cramps. How often do you girls get delayed due to emotional issues or problems? How common this is for you all? And no, I’m not pregnant, no sex at all for months now! TÍA 💕
