So confused:/ ???

So this my second month using glow and first month tracking bbt and using opks. I take my temp every morning at the same time before I get out of bed or move lol I'm currently on cd 19 and even though I had irregular cycles before going on contraceptive pills and after my mc. My last few cycles after a few rounds of injectables have been 34-35 days. I have been using opks quite early on in my cycle this month and haven't got one positive yet! I'm not sure if anyone else uses clearblue easy but these are what mine look like? As well as my bbt chart? Sorry for all the pics but I took so many that they didn't fit in one lol 
Is my body still gearing up for ovulation or might I have missed my surge?
