Your cycle can easily go off track for a month or two after changes in diet, exercise or weight. A bleed ten days after your period, followed by a long gap, can happen with that kind of hormonal shift. Since the bleeding was heavy for a full week and about a month has now passed with no period, a check is still sensible. A gynaecologist may suggest a pelvic ultrasound and a hormone panel that includes
thyroid and
prolactin, and will ask about your recent eating and training. If your period hasn't come in the next two weeks, or heavy bleeding returns, please book that visit sooner.
