OVULATION - IS THIS POSITIVE? PLEASE HELP

Kirsty

So.. I started metformin CD 22 and by CD 27 i was like this... I have NEVER got a positive ovulation test in my life but I did start taking a lot of vitamins at the beginning of my cycle in Jan also, I had a clear blue static solid smiley on CD27 too. By CD28 I was back to extremely faint and no smiley face. Does this look promising? Have I actually ovulated 😭
