Massallah pertaining to Hajj

Assalamu Alaykum,
We are planning to perform Hajj next month InshaAllah. However, I am very concerned with issues regarding my menstruation, which is very irregular and I’ve been having istihaadha during the past months. I have seen a doctor and was prescribed bc pills but these are making me sick and I fear that the matter will become worse with the accumulated intake by next month. What would Mufti suggest to do plz?
