In the name of Allah the most Gracious the most Merciful
The answer to your question is as follows:
The above details show that you are no longer in your previous habit. In this regard, the ruling now is that according to the previous habit, if the bleeding stops, you should start praying, but if the blood appears again before ten days, then these days will be counted as menstruation and the prayers will be waived during the menstrual period. Making up those prayers is not obligatory on you. However, if there is bleeding even after ten days, then it will be counted as the blood due to disease. So, you have to perform Ghusl and offer prayers during these days.
(وإن) انقطع لدون أقله تتوضأ وتصلي في آخر الوقت، وإن (لأقله) فإن لدون عادتها لم يحل، وتغتسل وتصلي وتصوم احتياطا؛ وإن لعادتها، فإن كتابية حل في الحال وإلا (لا) يحل (حتى تغتسل) أو تتيمم بشرطه (أو يمضي عليها زمن يسع الغسل) ولبس الثياب، والتحریمۃ الخ (شامی باب الحیض 1/294)
