Am I stressing to early?

Since being diagnosed with pcos last month, I've started metformin and ended up starting my first period in almost 6 months. Now that it's over I've started using opks, cm tracking and attempting to check bbt (it's often unreliable since I have a 20 month old and sleep is often erratic). But considering I've only had 2 periods this year, it's hard to pinpoint when I may ovulate, if I will ovulate at all this month, as well as cycle lengths. When I got pregnant back in 2015, I had very regular 28-29 day cycles and I ovulated between cd 14-15 each time. Now I have no idea when I could. I'm currently on cd 13 and have been testing since cd 8 just to monitor what was going on. But as of today I have yet to get a positive opk. My opks have been getting darker since starting to test, and have stayed constant this last 2 days ( I usually test between 2-4 times a day). My bbt is pretty unreliable but my cm has went from nothing, to sticky, to creamy, and now pretty watery. When I got pregnant back in 2015 I used to have ewcm each month, but I have yet to get it recently. Do you think that I still may be yet to surge and still have a chance at ovulating this month? Sorry kinda long but just anxious after ttc for the last 8 months and finally felt like I had a real chance.
