I have been on birth control for 8 months now. Period stared 9/27/17 today is 10/12 so cd 16 and I still haven’t haven’t had a positive ovulation test yet.

I do have hypothyroidism but I’m in normal range. Is there anything I can take to help my body regulate? My cycles can range any where from 40 days then 60 days to even 5 months before I have a period. I have started eating only fruits and veggies. I cut out soda, pasta, bread. Im taking prenatal vitamins already.
