Bleeding for more than a week along with dizziness, weakness and breathlessness needs prompt evaluation, as this pattern can point towards significant blood loss affecting your haemoglobin.
Next Steps
Please see a gynaecologist soon, ideally within the next day or two, for a blood count and ultrasound rather than waiting it out.
Health Tips
Please don't delay this given the breathlessness, and keep your neurologist informed too since you're on seizure medication.
