so confused with fertility tracking. please help

trying to track ovulation and I'm so confused. (background= I'm 34, in my 20's my cycle was very irregular but seems to have evened out, we've been TTC 1.5 yr, had 12 week MC last Dec, we've been using preseed, geritol, evening primrose, prenatals, vitamins for DH). At first I was simply using clear blue advanced and apps (thinking it would only be a few cycles of course). Then I started using cheaper dip tests from CD5-CD17. Last month added bbt and this month I've started checking CM and position. I had an HSG test on CD7 (initially looks like all is normal, but waiting to hear from Dr). I'm currently CD13, Clear Blue Advanced has read High for last 3 days, bbt is staying low, but CM is still creamy, although each day it's increased slightly in amount. it seems I can't get all factors to align. I'm now so confused I have no idea if/when I'm ovulating. Can you still be fertile even if CM is cloudy?? am I looking at too many data points??
