Follicular lymphoma grade 1-2 stage 4 rituximab+bendamustine

I am 60 years old and just completed 5 cycles of Rituximab+ bendamustine with one more cycle to go. I was diagnosed with grade 1-2, stage 4 follicular lymphoma with bone marrow involvement in November of 2021. 

Up until now, I have not been doing any research on the internet for fear of information overload and also realizing others’ experience and prognosis can be different. However, as I approach the end of my treatment, I am becoming more anxious about the results of my treatment and the prognosis going forward. 

My final chemo infusion may well be delayed as my blood count ( esp WBC and platelet) are borderline acceptable. I may either have to undergo blood transfusion or my last chemo scheduled for the end of this month may have to be delayed. My bendamustine dosage was already reduced as a compromise during my chemo infusion just a week ago.

I am curious to learn from those who are similarly situated (age, diagnosis, etc) and specifically from those who are able to achieve complete remission following the rituximab+ bendamustine routine. And relapses? In general, how long a remission period can one expect before a relapse? And is Rituximab maintenance necessary or helpful in order to delay a relapse? I know these are questions better answered by my treating oncologist before my final chemo infusion but I would be interested to hear from others who have already been there and are similarly situated. 

Thanks in advance for any response. I just started reading some of the postings on this site and find them to be very informative, helpful and educational.
