Extremely LOW BBT ?

So, as you can see, I have crazy low numbers. This is my second month TTC but first month really steadily tracking my temps. I heard low temps indicate a low thyroid (actually why I got the thermometer months back when I had no insurance). I take Armour thyroid daily along with a supplement. I can't seem to get a positive opk but I have regular cycles (avg 29-30 days). Right now I am having sore boobs, and I'm feeling a bit of swelling in my groin glands. I'm nervous that I'm not ovulating or that my thyroid too low to conceive. Been BD'ing every other day. Any thoughts?
