Ovulation time

Hi

I'm almost 30.
I have my Ovulation at around 18-21th day of my cycle. (32-35 days)
I'm taking "Levothyroxine" for 7 months now.
For 2 successive months (4&5) I measured my Ovulation at 14th day (with exactly 28 day cycle) but again I'm having it around 18-21th day.
I'm trying to conceive.
Is there any serious problem not to ovulate at 14th of the cycle?
If yes, what is the problem with me and how should i solve it?

Thank you

Ovulating on day 14 is actually not that common. Many women ovulate both before and after that day. It just depends on how fast your follicle develop and mature. Good luck to you!
