Some people do get higher temps during they're Af, so don't worry about it to much.
You will get cross hairs after 3 high temps following 6 low temps, it doesn't look to me as if your anywhere near a fertile window yet, OPKs will help with those.
Don't worry about checking your cervix just yet, iv TTC 3 times and I'm still not sure what I'm feeling for, as a guide iv read that if you look at yourlongest finger, it's got three lines, the tip, the middle and the Base, if you feel with that finger and just the tip is inserted it's low, the middle it's middle, if the whole finger goes in to feel for it then it's high.
As for cervical mucus, I'm still none the wiser, however I only got half an hour of ewcm this month and I have my BFP yesterday.
Keep on temping, with any luck your temps will drop now and you will see a fertile window, don't forget to do it at the same time everyday and try and keep your sleeping conditions the same
