Feeling optimistic!

Caroline • Ttc for 5 years now. We just lost our sweet baby at 18 weeks due to pprom. Heartbroken but have been given the ok to try again.
Back story: I have not ovulated on my own (without meds) in 4 years. I have been on Metformin for 4 months. The last 3 months have been medicated cycles and I've ovulated 2-3 follicles each month (still haven't conceived but at least I'm ovulating)
 NOW FOR THE EXCITING PART! 
We decided to take a month off from IUIs a meds. But my Dr wanted to check a cyst that has developed so I went for an US today. 
TURNS OUT I AM OVULATING ON MY OWN!!!!!!! 
Just thought I'd share :) baby dust to all!!!
UPDATE
I am on cd18 and still haven't had positive opk. Not sure why :( it's been a week since my US so I think I should have ovulated by now. Will talk to the Dr about it next week
