Query for Mavenclad Patients

Hi everyone. Hope everyone's having a good day. I started Mavenclad - Year one in 2021 and was due to take Year 2 pills end of January, 2022. However, Omicron hit me so my neurologist pushed it back by 4 weeks. I have had all my MRI Scans and blood tests and due to take it next week, and emailed my doctor informing her that. So she emailed me that everything looks good to start and when I saw my blood work, my lymphocytes were at 0.9. Should I be concerned? Or doctors know best? I'm trying not to overthink this.
