A high RDW like this, together with your low haemoglobin, MCV and MCH, points to a longstanding iron deficiency anaemia. It's not something to panic over right now, but not something to leave either. Two weeks of heavy bleeding with clots is enough blood loss to explain these numbers.
Next Steps
Please see a gynaecologist within the next day or two, both to manage the bleeding and to start iron replacement. Mention exactly how many pads you're using a day and whether you're passing clots larger than a coin. Go to a hospital the same day if you feel dizzy standing up, breathless, or your heart is racing.
