My previous charts seemed normal... and this month, I'm so confused

I went from CH's on CD 8, 14, and 16, had them come and go for days and now what? I've never had temps so low or so erratic. This is obviously going to be a very long cycle and I don't even know if I'll O. I'm getting to the point where I want to cry when I take my temp... will take it 3 or 4 times with 2 dif thermometers because on days like today I can't believe what it reads.
I'm upset, and I'm just wondering how everyone else gets through these cycles when they have them?
I"m also frustrated because in reality I won't get any answers till the New Year. My bloodwork is next week, but the earliest I can get in for an ultrasound is Dec 17th, my doc said she wanted to me to book an appt with her a week after they were both done, which would be Xmas time so that won't work.
I haven't been posting much because I'm just deflated, this cycle really has sucked the wind outta my sails and I hate to spread around my negativity
