myo-inositol, safe for anyone?

I have suspected PCOS. Haven’t had tests run yet, but I show some signs. Nothing that my doctor was concerned about to actually test. I did start taking myo inositol and d chiro about 2 months ago and started spotting mid cycle for about a week for 2 cycles. I stopped taking it out of fear because we would like to start trying for baby #2 in the next couple months. Is this a normal side effect? Should I stop taking it? I thought I heard anyone can take it so even if I don’t actually have PCOS I figured it was fine. My cycles have always been slightly irregular but more so since I had my son last year which is expected. I was hoping it would regulate me and help egg quality.
