Hi, Johanna:
The only way your doctor is going to know whether a treatment is working for you is for you to communicate your symptoms to him/her. When it comes to drug treatment, in particular, different bodies respond differently to different dosages, respond well to one drug and not another, etc. So, yes, I would say that you need to tell all this to your doctor. It would help, too, if you can remember approximately when symptoms started. And, depending upon WHEN in September your next bloodwork is scheduled, you might consider not waiting until then to ask for new bloodwork to be done. If it is the end of the month, for example, I would not wait. I would call now.
I hope you are feeling better, soon.
