is it possible that i am not ovulating on my own

Daisy

this is the second month I'm tracking my ovulation and I have nothing but circles up to so far. from Cycle Day 8. I've been on Euthyrox for about 9 months now changing over from Eltroxin. how long should I anticipate this non-ovulating period will last for or should I just keep tracking? when do I contact a specialist?
