Hello and welcome - We are fellow patients here and can't give medical advice…I wish I had more insight to offer for your situation. In normal times, we'd encourage you to contact your doctor about getting labs done to see if your dose needs to be adjusted. At this point, all I can say is to stay in touch with your doctor, especially if your symptoms worsen. (Perhaps they have a telemedicine option?) It will be a judgment call as to whether your need to get levels checked outweighs any risk of going out. (Especially if you are in a state with a shelter in place order.
Wishing you all the best, especially with three little ones at home!
