Hello,
This is normal during the first few years after menarche (the onset of periods). it is common for menstrual cycles to be irregular as the body takes time to establish a regular hormonal pattern. The cycle length may vary, and the flow can also differ from one cycle to another.it can vary anywhere from 21-45 days generally ..
If you mean changing a sanitary pad every 4–5 hours, that is generally considered normal.
You should consult a doctor if:
* There is a gap of more than 45 days between periods.
* The bleeding lasts for more than 7–10 days.
* The flow is very heavy (such as soaking a pad every 1–2 hours or passing large clots)
Ensure she maintains a balanced diet, drinks plenty of fluids, practices good intimate hygiene, and uses a warm compress over the lower abdomen if she has menstrual cramps.
This is not related to the vaccine.
