Early ovulation and no ovulation

So I always know when I ovulate as in alot of pain on one side & feel awful..

I had 1 really horny ovulation a few months back that I hadn't had in ages, since then my last 2 ovulations were on day 11 which has always been day 14 & this month i don't think I've even ovulated..

Im 44, nearly 45..

This happened to anyone else

My worst symtoms are anxiety and panic
