I have gone through the query and understood your concern. It is not normal to have such a type of bleeding. It definitely suggests hormone imbalance
. The periods which you had after hormone intake are due to withdrawal. The menstruation
which you observed soon after can either be a natural cycle once the transient hormone imbalance has settled down, or a persisting hormone disturbance. If you can chart your menstrual calendar for the next 2-3 months and see, you can know the difference. If the disturbance is persisting, you have to go for further investigation to plan management. Please maintain a healthy weight, regular exercise and a healthy diet. Take care.
