Blisovi 24 Fe

I’m 9weeks PP and my midwife prescribed me this BCP. I started it Tuesday morning 1/16 and started spotting then. Now I have like a period and it’s terrible and the flow is just getting heavier and heavier each day that passes by. She mentioned to me that if I feel terrible on it or bleed to not hesitate and give her a call to switch pills. This is what I plan to do Monday morning. My question is should I stop the pill or continue taking it until she sends another prescription for a different pill?
