Apparently still irregular cycles, not ovulating every month...help?

Hi! I'm new to Glo and hope I'm not messing up this post, this is my 1st one. This cycle will be the third one that we've been TTC. Before I went on Metaformin, my cycles were between 19 and 90 days. My Dr put me on it to lose weight, I'm not diabetic or IR, and it made me have what I thought was considered very regular cycles, they're now between 28 and 33 days. I just found out that isn't considered very regular, but rather still irregular! For the past two months I've been charting BBT and keeping track of CM, and I've discovered that while I ovulated the 1st month, I didn't the 2nd. Do y'all think it's because of the irregular cycles? I have PCOS, hypothyroidism, and other medical conditions. I'll be 34 next month so I'm in a hurry to get preggo. I've been reading about herbs to try, but don't know what's safe or what one(s), or even if I should try them. I know I need to lose weight and I've started meditating to bring down stress levels and for frequent insomnia. I'm going to start exercising again. What else can I do? Sorry this is so wordy and long, I just don't know where else to ask these questions. Thanks, and I hope I did this post right!
