Hi to all!!

Just wondering if anyone could tell me how many days before AF should your temp dip, and does it always dip before it!! my temps are still around
36.9-37.1 and im in the middle of that very stressful 2 week wait!! :roll: my af should be due around tomorrow and am wondering if it should have dropped by now and is it a good sign that it is still high??? [-o<
I have taken a fortel ultra test and got a very faint positive but did a crystal clear this morning and got nothing!
As you can see im clining on to any hope!! 8-[

Love to hear anyone's advice
