Ovulation 5 days before period

Hi everyone,
I am on synthroid for three months now. From the past two months, I noticed that my ovulation is occurring 4-5 days before period and that would mean my LP is very low. Is it safe to conceive in such cases? Or should I wait till my LP increases?
My midwife brushed it off saying they did a progestrone test which was normal and my opk tests could be wrong but this is the second time it is happening. I am afraid synthroid affected the LP. What options do I hAve now ? Please pour in some thoughts- I am really tensed. I will meet my obgyn soon.
